Today we (Terri, Skylar, Yajaira, Chris, Ryan and Bob) went to the estuary meadows of the Hamilton River to look for a place to install a trail camera. We are hoping to capture photos of Moose, Bears, Wolves, Mink, Marten and other wildlife that may be using the area. We took the Hamilton River Trail down to the meadows but we did not want to install the camera on the people trail, even though it is likely a popular trail for wildlife too, because we did not want to be taking pictures of people without them knowing about it.
Testing the trail camera on the bear trail near Hamilton River.
We talked about how vegetation provides food and cover for wildlife and how if we understand how to identify food and cover values in wildlife habitat we can use that information to choose a good location for setting up the trail camera. We also talked about animal sign and how there are two important categories for it: ephemeral sign only lasts for a little while, like tracks and scat; and perennial sign lasts a long time like well-worn trails and sign trees.
We decided to pick an area that provided food and cover for as many species as possible so we looked for some big trees (cover) that were next to shrub thickets (foods in the form of berries and woody browse), meadows (food in the form of herbaceous leaves, stems and roots), and the river (food in the form of salmon).
After hiking to a spot with good food and cover values, we looked for perennial wildlife sign and found both a well-worn trail as well as a set of sign trees. There was even some ephemeral sign in the form of bear scat and a bear bed along the trail (look close in the photo). We found a good mounting tree that could take in the view of the trail and we set up the camera. Then we tested the camera by taking turns walking the trail like a bear or wolf might do.
That was fun.
Students from the Klawock Middle School hike through the Harris River Interpretative Site.
Spring is turning into summer and schools around the nation are releasing their students to a well-deserved vacation. The schools in Klawock, Alaska are no exception. There’s a catch however. Before letting kids head home for summer vacation, the Klawock School District is releasing students into the woods.
On May 24th, teachers Abe Horpstead and Corby Weyhmiller loaded 18 students from the Klawock Middle School into vans to go on a field trip put together by a diverse group of professionals who make their living working in the woods.
Weyhmiller, of Klawock City School District, stated “This was a great opportunity for students to learn in the greatest classroom we have available. Our students had a blast learning from nature and seeing local people that have made a living that allows them to explore, protect, and manage our natural world. ”
Bob Girt of Sealaska Timber, along with Gary Lawton, a forestry and silviculture consultant for Sealaska Timber coordinated with Stephen SueWing, a Development Specialist with the State of Alaska Division of Economic Development, Michael Kampnich of The Nature Conservancy, and Quinn Aboudara a community catalyst with the Sustainable Southeast Partnership and Klawock Cooperative Association to engage local youths. Kai Environmental Consulting Services, based in Southeast Alaska generously provided lunch for these students and instructors in the field.
Bob Girt of Sealaska demonstrates some of the equipment used in many forestry careers.
Eighteen students from the Klawock Middle School first stopped along the Klawock Lake watershed where introductions were made and the students were able to speak with Aboudara. Aboudara spoke of the many restoration and research projects throughout the watershed. The students asked questions in regards to local sockeye salmon populations and possible careers in research fields.
Next, the students met Bob Girt and Gary Lawton at the Harris River Interpretive Site, a United States Forest Service experimental forest site that demonstrates various land management prescriptions such as different forms of tree thinning. Lawton, who had worked for the United States Forest Service for thirty-six years, discussed some of the benefits of the various forms of tree thinning as well as the numerous career paths associated with the Forest Service. Girt, demonstrated various types of equipment used by many in forestry careers.

The students then joined Michael Kampnich at the Harris River Campground, where they learned of The Nature Conservancy’s role in a number of projects around Prince of Wales Island, including genetic sampling of wolves, various restoration projects around the island, and supporting the various works engaged in by multiple tribes and other interested organizations.
This field trip is one of many ways in which the State of Alaska’s Division of Economic Development has been partnering with local tribal organizations such as Klawock Cooperative Association and the Organized Village of Kasaan, regional corporations such as Sealaska, other interests such as The Nature Conservancy, and local schools to engage with youth to foster opportunity and interest in the forest and promote local workforce development.

Public lands surround Southeast Alaskans. The 17 million acre Tongass National Forest is where residents go to hike, camp, fish, and gather food to nourish their families and wood to warm their homes. It’s where kids hunt their first buck and where friends gossip while munching on succulent salmon berries.
There are other integral values that Southeast Alaskans derive from public lands too: economic values. Tourists flock to soak in vast untrammeled Alaskan views and the majority of salmon begin their lives in streams among the trees. There is untapped economic opportunity as well and in Sitka, the United States Forest Service (USFS) and local entrepreneurs are exploring options for cultivating small businesses using resources on public lands.
Salvaging a business on the Tongass
Zach LaPerriere grew up in Ketchikan but has since built his home and raised his family in Sitka. He’s always gravitated toward the woods.
“From boat building to construction, woodworking has always paid the bills for me,” LaPerriere said.
He runs a business out of his humble one-room home nestled in the forest. In his open studio overlooking Silver Bay, he turns bowls from dead trees that he salvages from the Tongass National Forest.
“Making bowls satisfied something in me because I was involved at every single step in the process from selecting and harvesting the raw material in the forest right to handing a customer a finished bowl. That really attracted me,” LaPerriere said.
“Making bowls satisfied something in me because I was involved at every single step in the process from selecting and harvesting the raw material in the forest right to handing a customer a finished bowl. That really attracted me,” LaPerriere said.
He’s building his business from the ground up, literally. Wandering through the temperate rainforest, LaPerriere seeks out ideal dead trees, applies for the necessary permits, turns the bowls on his lathe, grows his business and hones his technique as he goes. His family partakes in the process and his wife Jenn Lawlor supports with marketing.
“Local woods are harder to turn and they take more skill but we live a deliberate life here where we try to live as local as we can and stay connected to this vast place. We don’t buy meat, we don’t buy fish; it all comes from the forest and ocean here,” he said.
LaPerriere is also deliberate about his choice to salvage wood on public lands.
“Public lands are getting used here and are providing jobs in huge ways with tourism and fishing for example but there is tremendous untapped potential and that is part of the reason I pursued getting wood off of public land versus private. I really felt like why not be an example for what can be done here,” LaPerriere said. “I’m not getting rich off of a new business making bowls but it is something and it is contributing to my family’s livelihood and it’s growing. It takes a few people to show what change can be done on the Tongass.”
And his customers love it too. “It’s a way for me to show people, like this gentleman in Ohio who just bought a couple of my bowls for example, his public lands. That wood came from his forest and that’s amazing. Even if he never comes to Alaska, he is going to have a little piece of a tree on the Tongass that he and more than 300 million other Americans share,” he said. “It’s meaningful.”
Spruce tips, mushrooms, berries and more
LaPerriere isn’t the only individual hoping to catalyze small business exploration on public lands. The Sitka Ranger District (SRD) is making headway in the region.
“Right now, we have the first special forest product permit issued on the Tongass ever to my knowledge and it was for 150 pounds of spruce tips this year,” SRD District Ranger Perry Edwards said.
Special forest product permits are issued for the commercial use of forest resources like berries, spruce tips and mushrooms. This particular permit is being used to explore selling spruce tips to home beer brewers across online markets.
Harvesting resources like spruce tips and berries requires a public review process. The Forest Service adheres to the National Environmental Policy Act (NEPA) process to ensure that commercial activity on public lands does not harm the environment and is done so sustainably, responsibly and in the best interest of the many stakeholders who share rights to these forest resources.
“We have NEPA — cleared up to 10,000 pounds of spruce tips from the Sitka Ranger District. We worked with the Sitka Tribe of Alaska, community members, and our silviculturist and biologists to look at every possible angle to ensure proper management. There are caveats on where you can collect them and how. You can’t collect them from trees of a certain height for instance and you need to tell us where you are getting them from so that we can monitor use and learn about the impacts,” Edwards said.
Since SRD has now received NEPA clearance for up to 10,000 pounds of spruce tips to start, interested individuals can apply for commercial spruce tip picking permits in the district without having to go through the entire public review process from the beginning.
“I’d just love to get the NEPA done for more of these forest resources. Down south there are a lot of entire forests that have a special forest product plan in place for the whole forest,” Edwards said. “For example, on the forests that have big fires, whole tent-towns spring up to harvest morel mushrooms and they make hundreds of thousands of dollars doing that,” Edwards said.
“We might not have the mushroom thing in that quantity but jeez, I look outside and I see spruce tips and I see blueberries and I don’t know how we could ever pick out the blueberry crop,” Edwards said.
The permit process looks different depending on the request, the size of the harvest, the type of resource, the location etc. For example, LaPerriere’s permits for salvaging dead trees was processed as a timber permit and did not require a public review process in part due to the quantity and nature of his request (only a handful of dead trees a year). The recent spruce tip forest product permit for 150 pounds in Sitka did not need to go through public review because the SRD had already NEPA cleared 10,000 pounds.
There is opportunity to be creative. Groups of harvesters could combine efforts and apply for a permit to pick berries to sell wholesale, for example. Edwards explained that tribal governments or organizations could even apply for permits to pick, say 10,000 pounds of blueberries and administer smaller permits among tribal and non-tribal citizens. The most efficient and appropriate required permit and process will differ based on the resource you seek and your plan but the USFS is more than just receptive to the idea, they are encouraging, excited to work with more Alaskans to develop business plans based on public lands.
“I would love to see more of these and see more people come in. Like with Zach’s stuff, I never would have thought of that business in a million years. I keep going to my typical berries and chanterelle mushroom examples but spruce tips too,” Edwards said. “I never would have thought of that.”
If you are interested, develop a business plan and start crunching some numbers.
“Come to us early on and say ‘Hey I have this idea, how can we make this happen.’ Don’t come to us and say, ‘Hey, I need this and this needs to happen tomorrow or this month,” Edwards said. “Depending on the proposal it could take 5-6 months maybe less, maybe more.”
The cost for the permit is determined by the resource, the amount, whether you intend to sell wholesale or retail. It’s all determined case by case. If you have an idea, Edwards recommends you call your local Forest Service office and start the conversation and begin to research.
“We would be happy to work with you. We are absolutely open to it. I love the idea of people coming to me with new ideas, I’m waiting. I’m here with the government and I’m waiting to help,” Edwards said.
A country founded on small business
Back at the lathe, LaPerriere is busy churning out between 150-200 wooden bowls a year and he’s seeing growth and encouraging others to explore their own ideas.
“If anyone is interested in this, fire it up, try it out. If you like making jam, try making a bigger batch, talk to the Forest Service about harvesting off public lands. Start small and scale up,” LaPerriere advised.
“The Forest Service has gone from adversarial to small businesses to wide open arms. I could not ask for a more encouraging agency to help make the process as simple as possible. They see the value in small industry because our country was founded on small business! Some things come and some things go but small business will always be here,” LaPerriere said.

Katlian Street in Sitka is a bustling cultural and fishing hub. Along this winding harbor-side road, tightly squeezed between fishing gear shops, processing plants, and docks crowded with scavenging gulls, is the Sitka Tribe of Alaska’s (STA) Resource Protection Department building.
While the building’s salt-worn front doors look unassuming, behind its modest exterior is a state of the art laboratory dedicated to harmful algae bloom monitoring and shellfish research. This year, the lab will add ocean acidification monitoring to its impressive coastal monitoring toolkit.
The Southeast Alaska Tribal Ocean Research partnership (SEATOR) was formed by the Sitka Tribe of Alaska in 2013 as a network of tribal governments, universities, and nonprofits to monitor harmful algae blooms in the state.
“Alaska is the only state where people still die of Paralytic Shellfish Poisoning,” explained Chris Whitehead who is the Environmental Program Manager at STA. “Alaska was the only state that didn’t have a monitoring program in place and we have such huge levels of toxins so it was very disconcerting.”
Before heading to Sitka to work with STA, Whitehead spent years working in Washington with tribes and researchers monitoring shellfish populations for toxins. So, when a group of community members and local elders inquired about setting up harmful algae testing in Sitka, Whitehead stepped in.
“It was just good timing. There was a need, and I was able to bring up experts I had met in Washington to help set something up locally. Then we went to work writing grants and securing funding,” Whitehead said.
Today, the lab monitors plankton samples under the microscope, tests for harmful toxins and sends out warnings when toxin levels are too high for safe foraging.
“We want to be as proactive as possible to catch a toxic event before anyone gets sick. That means every week, we collect plankton and water samples to make sure there are no active harmful blooms. In addition, we collect blue mussel samples every one to two weeks since they are the first species to pick up toxins and are not widely consumed. If we see any indication that toxins or harmful plankton are rising, we preemptively issue a community advisory, increase our sampling frequency, and start testing all shellfish species,” said Esther Kennedy.
Kennedy was born and bred in Alaska. She returned after receiving a BA in Earth and Planetary Sciences from Harvard University to work with Sitka Tribe and can often be found pulling plankton nets through Sitka’s shoreline.
Of course, Sitka is not the only community where avid shellfish harvesters punch rusty shovels into sand and grit in pursuit of delicious bivalves. Fifteen other tribes in Southeast Alaska also employ specialists who peer through microscopes for dangerous plankton and send water samples to STA for toxin tests every week.
Carrie Davis fills this role for the Organized Village of Kake. She shares updated information about shellfish safety for this community of 600.
That information has given Kake resident John Williams Sr. greater confidence when harvesting this important cultural resource. Williams, 65, has been setting out by boat or by foot to dig for clams and picnic with loved ones for as long as he can remember.
“I’m always talking to Carrie and she posts it on the community board there, to show us where it’s safe and it’s useful because we know where to go and where to stay away from,” said Williams who can now share his chowder and cockles with less worry.
Climate change’s under-recognized twin: ocean acidification
Since the lab began monitoring efforts in 2013, nobody has become ill or died from Paralytic Shellfish Poisoning on any of the studied beaches. Success, one might say, has spread like a sunlit plankton bloom.
“When it first started, it was just six to eight tribes and now it’s 15 tribes in Southeast, four sites in Kachemak Bay and a handful of tribes in Kodiak that are starting up,” Whitehead said.
And the network isn’t just growing geographically.
“When this all started, the tribes hadn’t worked together in this capacity regionally before. Once this began, it really opened the door for the tribes to ask, ‘What else do we have common concerns about, what else can we work together on?’ and climate change was at the very very top,” Whitehead said.
That comes as no surprise. Alaska is warming faster than any other state.
“Ocean acidification, global warming’s under-recognized twin, is also affecting Alaskan waters faster than any other state,” said Kennedy.
“As carbon dioxide dissolves into the ocean, it becomes more acidic. It’s a global problem, but colder Arctic waters absorb more CO2 so it’s hitting us especially hard. Acidification makes it difficult or impossible for creatures like shellfish, crustaceans, and pteropods to make shells. This is bad news because it decimates the foundation of the marine food web,” Kennedy said. “We depend on the sea for everything in Southeast Alaska. It’s hard to imagine that we will be unaffected by ocean acidification.”
So the SEATOR team went to work figuring out how to tackle a challenge as far-reaching and daunting as ocean acidification. That’s where the “Burke-o-Lator,” a scientific instrument which Chris Whitehead called the global standard for measuring ocean acidification, comes in. Burke Hales, the scientist who created it, will be headed to the Sitka lab in mid-May to help install this new addition. He’s excited for what this data set and network will mean for ocean acidification research globally. With more than fifteen tribal governments across the region contributing to the monitoring efforts, SEATOR will paint a representative image of how ocean acidification is impacting a large geographic area.
Chris Whitehead and the entire SEATOR network are excited for what the data set will also mean locally.
“There is not a lot of ocean acidification work being done in the Southeast,” Whitehead said.
“We will have a good data set in Sitka and these other communities across the Southeast will submit their samples and it will all contribute to a robust local picture. And here, we have 15 tribes working together to provide this big data set and not a lot of people are doing that nationally.”
Geoducks and upcoming scientists
Climate Change monitoring is not the only new addition to SEATOR. The lab is working on getting FDA approval to administer PSP testing to Southeast Alaska’s commercial dive fisheries. For geoduck fishermen, this will mean more streamlined and local testing opportunities and a longer harvesting window.
The lab is also dedicated to building capacity among Southeast Alaska’s upcoming scientific leaders. On Thursdays this spring, several Mount Edgecumbe High School students filed into the lab, donned authoritative white lab coats, pulled mussel cages, homogenized tissue, ran genetic testing, peered through microscopes, and analyzed results. They were part of an internship program aimed at preparing the next generation of scientists for meaningful careers in applied research. Sienna Reid, who is both one of those students as well as a member of the Sitka Tribe of Alaska, is heading to Western Washington University this fall to pursue a degree in science.
Energy is building for these programs, and not just among the tribal governments who are actively participating.
“Senator Lisa Murkowski, Sullivan and Don Young too have all been very supportive of ocean acidification work. It’s a bipartisan issue, regardless of your views on climate change, it is clear that the oceans are acidifying and that is going to affect Alaska’s fisheries, so when we have spoken to those offices they have been really excited about doing this work,” said Whitehead.
Of course, like all grant-funded efforts, there is uncertainty.
‘“We are in the same boat as everyone else, waiting to see what happens for Fiscal Year 2018. EPA dollars are the backbone for this. We have other funding in Sitka but the tribes across the region who are doing the consistent weekly work are almost 100 percent funded by EPA dollars,” said Whitehead. “So we are hoping that these programs don’t get targeted.”
SEATOR started as an idea four years ago. Today, it’s helping to not only provide safe access to an important subsistence resource, but is also leading the way in ocean acidification research. All the while, this humble beach-side laboratory is providing opportunities and building capacity for the future stewards of Alaska’s coastal health. In a state that depends on coastal resources for everything, that is certainly something to celebrate with a community clam-dig.

FOR IMMEDIATE RELEASE
March 21, 2017
(Thorne Bay, AK)— This week on Prince of Wales Island, 13 students attending the second Forestry Training Academy are proof that collaboration can be more than just a buzzword. The Forestry Training Academy is two weeks of training to prepare students for local jobs in natural resources. The U.S. Forest Service, state Division of Forestry, state Division of Economic Development, Sealaska Timber, Spruceroot Community Development Fund and Sustainable Southeast Partnership are working together to support the academy for a second year.
Why are federal, state, private and non-profit groups all invested? Each share a common objective to support sustainably-managed forests and sustainable communities with healthy economies. The academy puts local people to work in local jobs, gathering valuable data about area timber stands. Land managers across the region have forestry jobs to fill and the partners believe that keeping jobs local is good for industry, good for communities and good for Alaska.
“We are interested in a strong regional economy and working forests managed by a trained, local workforce,” said Sealaska President and CEO Anthony Mallott. “Maintaining a focus on sustainable harvests helps achieve that.”
The academy is an outgrowth of the Tongass Advisory Committee (TAC), a federal advisory committee formed while the Forest Service was amending the Tongass National Forest management plan. The TAC brought together stakeholders from the timber industry, environmental groups, Sealaska, and the State of Alaska to advise the Forest Service on how to support the transition to young-growth timber harvest and provide for a viable forest industry in Southeast Alaska. Among its final recommendations in late 2015, the TAC recommended investing in a skilled local workforce as an integral piece of developing a more sustainable timber industry.
“The workforce academy is a key element of the new Tongass Land Management Plan, put into action. It’s good for the region and it is an improvement in forest management,” said Andrew Thoms, a TAC member and executive director of the Sitka Conservation Society.
Last year, eight students graduated from the academy equipped with place-based natural resource skills and knowledge immediately transferable to local careers. The Division of Forestry immediately hired six graduates and Sealaska Timber offered a position to another. In December, two of the graduates working with the Division of Forestry on young growth inventory were offered long-term positions with the Forest Service.
Collaboration has proven essential for supporting the academy and the partners also believe that collaboration across land managers is good for sustainable and effective land management.
“This is part of the USDA’s All-lands approach to land management. The Forest Service is working together with the State of Alaska and adjacent land owners to develop a more robust and sustainable approach to forestry across our region,” said Beth Pendleton, Regional Forester for the U.S. Forest Service-Alaska Region, currently serving as the Acting Associate Chief of the agency in Washington, D.C. “The Forestry Academy also helps carry out the U.S. Forest Service Alaska Department of Natural Resources TAC’s recommendations to develop a local workforce and to support the inventory of young growth timber,” she said.

Alaska State Forester Chris Maisch added, “This team effort is producing impressive results in both the classroom and in the woods. No single organization has the required talent and capacity to accomplish the training and the ensuing project work on its own. The new hires have a great work ethic and pick up new skills rapidly through their work with our forestry team.” The second Forestry Training Academy started on Monday, March 20 and is underway until March 31. It will cover basic forestry skills, best practices, U.S. Forest Service safety requirements and Division of Forestry inventory protocol. The training will also offer students classroom and in-the-field instruction to practice, develop and test skills. Twenty-eight applicants competed for 13 openings this year. All 13 students are from Alaska: four from Ketchikan, one from Haines, one from Metlakatla and seven from Prince of Wales Island.
“Prince of Wales is my home and I am motivated to help sustain and safeguard what is left of the Tongass. I am ready for new challenges within the dynamic environment that the Forest Service represents,” said Christa Hambleton, an academy participant from Port Protection. Hiring local workers allows people in rural communities to stay, work, and raise families in their traditional homes. And many of the natural resource jobs are year-round and well paying. Hiring local allows more money to circulate in the economy and helps create more sustainable communities. Graduates will qualify for immediate employment opportunities with the Forest Service, Division of Forestry and others.

Since the field season of the Hoonah Native Forest Partnership (HNFP) concluded in late October, 2016 there has been a lot of hustle-and-bustle behind the scenes as partners analyze the datasets generated by crews throughout the summer. Three of the key analyses hinge on the use of LiDAR data which was flown over >200,000 acres of the island. One analysis seeks to determine vegetation characteristics based on timber stand characteristics. The other two analyses focus on creating an intrinsic potential model of Pink and Chum Salmon habitat and modeling barriers to fish. Each of these analyses will provide direct information leading to better management of the landscape and rivers.
The goal of the HNFP Vegetation Study is to provide a very detailed map of both forested and non-forested vegetation types for use in timber, fish and wildlife planning as well as to support local residents in their efforts to gather resources for their households and businesses. The methodology being used combines field data collection and aerial photo classification with LiDAR derived vegetation structure and landscape position data. This is the cutting edge of vegetation mapping on planet earth. The use of LiDAR to model vegetation structure and topographic features can dramatically cut the amount of time that traditional methods take to reach the same end. In order for the LiDAR data to be useful, crews surveyed random forest plots (n=111),as well as stratified sampling for non-forest plots (n=208) across the landscape. Forest plots were created from the LiDAR data by combining the openness of the forest structure (open, sparse, gappy, closed) and the height ( short, medium, tall) and a random selection was generated from that. Non-forest plots were selected to cover the range of spectral signatures that occur in four-band orthoimagery acquired for the project area.Plot categories were linked to landscape characteristics that drive plant community dynamics such as elevation, aspect and slope. Because of this stratification across topographic characteristics crews had to survey from sea-level to mountaintops at 3,000 feet. At each plot the crew followed a Forest Service protocol requiring them to identify every species of plant within the plot, as well as its percent composition. They also measured the diameter at breast high (DBH) and height of each tree within the plot.
The data generated by the crew proved to be invaluable to the analysis. Vegetation study leads Conor Reynolds and Bob Christensen are using this analysis to estimate potential for future timber harvest, model deer habitat values under various management scenarios, identify locations to promote blueberry production and estimate future wood availability for salmon habitat maintenance in riparian stands.. This is particularly important in streams where logging occurred up to the river’s edge (before the establishment of the Alaska Forest Practices Act) and large logs are not falling into streams with enough frequency to maintain fish habitat.
“The benefit of the forest inventory to land managers would be that we’ve created a uniform dataset covering the variability of the entire landscape that effectively tells us the size and density of forest cover. This allows for more targeted scheduling of management activities mitigating the negative effects of intermediate stand stages on other resources such as deer and berries.”

Creating an Intrinsic Potential Model
In order to manage a landscape effectively, it is important to forecast future scenarios and to know the potential of existing habitat. Due to the access difficulties and prohibitive costs associated with conducting extensive on the ground population surveys across large area of rugged southeast Alaska, decision makers are turning toward tools based on remote sensed data for evaluating the associations between salmon populations and their critical freshwater habitat. Bernard Romey, a graduate student, set out to create an intrinsic potential (IP) model that predicted habitat suitability at the landscape level for spawning chum and pink salmon based on LiDAR derived persistent habitat characteristics such as slope and mean annual flow. Previous intrinsic potential models have been created in Oregon for steelhead trout and coho salmon, however, the IP models created through the HNFP will be the first Southeast Alaska specific chum and pink salmon models. They are likely to benefit communities and land managers across the Tongass National Forest.
“Our chum and pink salmon Intrinsic potential models, paired with the NetMap stream network analysis software, are powerful leading-edge GIS-based tools that will allow decision makers a ‘first step’ approach for predicting broad-scale areas of potential high quality salmon spawning habitat.”
— Bernard Romey
Modeling Barriers to Fish
The ability for a salmon to travel upriver to its original spawning ground is truly remarkable, but even their exceptional skill is limit as streams become steeper, skinnier, or laced with barriers. Knowing the upper limit of salmon distribution is important for guiding management decisions to avoid disturbance of spawning habitat and to protect salmon populations. The fine-scale resolution of the LiDAR can be used within the NetMAP toolset to predict the presence of passage barriers such as waterfalls or steep cascades. Crews walked upstream to survey the height and gradient of potential barriers. These data are being used along with Lidar to refine the barrier prediction model and to develop a map of all salmon streams in the region.
A Model for the Future
The products derived from the LiDAR for the Hoonah Native Forest Partnership are an emmense benefit. It is our hope that as future LiDAR projects are flown, that our results and methods may be used in future community forest products looking to streamline the process of collecting forest metrics and modeling habitat.
“The results of the vegetation mapping work we are doing for the HNFP are important because it provides a much higher resolution, and more detailed vegetation map for all private and public lands that surround the community of Hoonah. Consistent, reliable and up-to-date natural resource data in the jurisdictional patchwork of public and private lands that is common in areas surround rural communities in southeast Alaska has simply been non-existant up to this point. Historically, this state of affairs has undermined resource assessments that are best conducted at the watershed scale so we are particularly lucky to have access to this new product for the HNFP.
Furthermore, the additional detail in this vegetation map will support much more strategic, collaborative and cost effective project planning and implementation for timber, fish and wildlife resources. In the end, these results will save land owners and managers money, enhance returns on their investments over time, and integrate improved outcomes for residents and visitors who utilize these lands for hunting, fishing, recreation and entrepreneurial endeavors.”
