Sitka Urban

The Sitka Urban Inventoried Roadless Area encompasses 112,003 acres on Baranof Island within the Tongass National Forest, directly adjacent to the city of Sitka in southeast Alaska. The area includes some of the most topographically varied terrain in the region: Gavan Hill, Mount Verstovia, Arrowhead Peak, and Mount Katlian rise steeply from tidewater, with The Sisters, Lucky Chance Mountain, and Annahootz Mountain forming the higher ridge system to the north. Indian River Valley and Billy Basin are the two major interior drainages. The watershed is of major hydrological significance: Indian River, Sawmill Creek, Katlian River, Cascade Creek, Granite Creek, Coxe River, and Vodopad River drain to Sitka Sound and Nakwasina Bay, while Heart Lake, Beaver Lake, Medvejie Lake, Glacier Lake, Cold Storage Lake, and Pinta Lake occupy cirques and valley bottoms throughout the area.

Sitka spruce (Picea sitchensis), western hemlock (Tsuga heterophylla), mountain hemlock (Tsuga mertensiana), and Alaska-cedar (Callitropsis nootkatensis) define the forest communities, with red alder (Alnus rubra) along disturbed stream corridors. At lower elevations, the understory is dominated by devil's-club (Oplopanax horridus), salmonberry (Rubus spectabilis), and oval-leaf huckleberry (Vaccinium ovalifolium), with stairstep moss (Hylocomium splendens) and lanky moss (Rhytidiadelphus loreus) carpeting the ground. Methuselah's beard lichen (Usnea longissima) festoons old-growth conifers. The Alaska holly fern (Polystichum setigerum), assessed as vulnerable by the IUCN, occurs in sheltered coves. Above treeline, segmented luetkea (Luetkea pectinata), western bell-heather (Cassiope mertensiana), and marsh valerian (Valeriana sitchensis) characterize the alpine zone. Muskeg openings in the mid-elevation forest hold common labrador-tea (Rhododendron groenlandicum), bog rosemary (Andromeda polifolia), and roundleaf sundew (Drosera rotundifolia).

Brown bear (Ursus arctos) and mule deer (Odocoileus hemionus) are the most frequently observed large mammals, with mountain goat (Oreamnos americanus) confirmed in rocky alpine terrain. Pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta) return to Indian River and Sawmill Creek, supporting bald eagle (Haliaeetus leucocephalus) concentrations and American dipper (Cinclus mexicanus) year-round on these creek systems. The sea otter (Enhydra lutris), IUCN endangered, uses nearshore kelp habitats in Sitka Sound. Pinto abalone (Haliotis kamtschatkana), assessed as endangered by the IUCN, occurs in the rocky intertidal and subtidal zone along the area's coastline. The marbled murrelet (Brachyramphus marmoratus), IUCN endangered, nests in old-growth stands and forages in adjacent marine waters. The sunflower sea star (Pycnopodia helianthoides), critically endangered, formerly dominated rocky intertidal communities here. Trumpeter swan (Cygnus buccinator) occurs on the area's lake systems. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

The Harbor Mountain–Gavan Hill Trail (4.6 miles) and Indian River Trail (4.2 miles) are the most heavily used routes. The Indian River Trail follows its namesake drainage from a road-end trailhead, moving through closed-canopy Sitka spruce–hemlock forest where the sound of the river is constant and the understory is dense with devil's-club and salmonberry. As the trail gains elevation, the canopy shifts toward mountain hemlock and the ground layer becomes more open. The Harbor Mountain–Gavan Hill Trail climbs from near sea level to alpine terrain, passing through all major forest community types before reaching the ridge where The Sisters are visible to the north. Beaver Lake and the Thimbleberry/Heart Lake are accessible via shorter trails, offering access to the area's lake systems within 1–2 miles of the Sitka trailhead network.

The Tlingit Kiks.ádi clan has maintained a connection to the shores of Baranof Island and Sitka Sound since at least 4,500 years ago, and archaeological investigations at the Hidden Falls site on Baranof Island's northeastern coast have documented human occupation dating to 8,000–8,600 years before the present. [1][2] The Kiks.ádi established a permanent winter village at Shee Atika—"people on the outside of Shee (Baranof Island)"—below what became Castle Hill, with summer fishing camps and resource areas extending along Baranof's coast. [1] Sitka Tlingit clans, including the L'uknax.adi, Kik.sadi, Kaagwaantaan, and others, organized their lives around salmon, sea mammals, and the rich marine resources of Sitka Sound, maintaining strict clan ownership of fishing grounds and trade routes reaching into the interior. [1][7]

Russian interest in Sitka Sound intensified after Aleksandr Baranov established a trading post at Old Sitka in 1799. [3] Tlingit tolerance of Russian presence eroded quickly, and in 1802 Kiks.ádi warriors attacked and destroyed Redoubt Saint Michael, a Russian outpost northwest of Shee Atika, killing nearly all the Aleuts and Russians stationed there. [1] The Russians returned in force in September 1804: after a naval bombardment, Russian troops stormed the Tlingit fortification at Indian River known as Shis'ki-Noow, but were bloodily repulsed. After a six-day siege, the Tlingit, out of gunpowder, withdrew quietly at night, and the Russians built their colonial capital, Novo Arkhangelsk, on the site of the Tlingit village. [1][2] The Tlingit returned to the vicinity in 1821 at the Russians' invitation, living in a settlement adjacent to the colonial stockade until the American purchase of Alaska in 1867.

Commercial timber use in the region predates formal federal management. By 1909, nearly all commercial timber in southeastern Alaska was incorporated into the Tongass National Forest. [5] President Theodore Roosevelt had established the Alexander Archipelago Forest Reserve in 1902 and created the Tongass National Forest by proclamation on September 10, 1907; on July 1, 1908, the Alexander Archipelago Reserve and the Tongass were formally merged into a single administrative unit. [3][6] The Civilian Conservation Corps arrived in 1933 to build campgrounds, trails, and roads in the forests and restore Native totem poles of southeastern Alaska. [3] During World War II, the Alaska Spruce Log Program intensified logging on the Tongass to supply aircraft lumber, directing harvests toward mills in Puget Sound. [3]

The postwar era established Sitka as the center of a large-scale industrial timber economy. In 1953, a 50-year timber contract was signed with Alaska Lumber and Pulp Company, committing 5.25 billion board feet of timber from a primary sale area including Baranof Island. [5] The company constructed a pulp mill in Sitka that was completed and operational in November 1959 at a cost of approximately $66 million, with an initial capacity of 340 tons per day. [5] The Sitka pulp mill closed in April 1994 following market changes and the termination of its long-term timber contract. [4]

Today, the Sitka Urban Inventoried Roadless Area—112,003 acres within the Sitka Ranger District—is protected under the 2001 Roadless Area Conservation Rule as part of Tongass National Forest.

Vital Resources Protected

Old-Growth Structural Complexity The Sitka Urban Roadless Area maintains 112,003 acres of old-growth Sitka spruce–western hemlock–Alaska-cedar forest on Baranof Island, preserving the complex canopy structure and large-diameter conifers required by the marbled murrelet (Brachyramphus marmoratus), IUCN endangered. The area also supports several IUCN vulnerable species specifically associated with old-growth microhabitats: the Alaska holly fern (Polystichum setigerum) in sheltered old-growth coves; Menzies' burnet (Sanguisorba menziesii) in forest margins; and the charred matchstick lichen (Pilophorus nigricaulis) and Platismatia lacunosa on old-growth bark surfaces. Logging, documented as an extreme-severity threat at 11–30% of the marbled murrelet's range, requires road access to old-growth forest as its primary enabling condition; the roadless designation directly prevents this access.

Riparian Function in a Multi-Drainage Watershed Indian River, Sawmill Creek, Katlian River, Cascade Creek, Granite Creek, and Coxe River drain a major watershed to Sitka Sound and Nakwasina Bay, with a network of lakes—Beaver Lake, Heart Lake, Medvejie Lake, Glacier Lake, Cold Storage Lake, and Pinta Lake—occupying upper basins. The roadless condition maintains intact riparian buffers along all of these drainages, preserving the stream temperature, large woody debris recruitment, and bank stability that support pink salmon and chum salmon spawning throughout the system. American dipper (Cinclus mexicanus), which forages year-round in these creek systems, depends on the macroinvertebrate communities supported by cold, well-oxygenated water free of road-sourced sediment and runoff.

Intertidal and Nearshore Habitat The rocky intertidal and nearshore zone of Sitka Sound and Nakwasina Bay supports the IUCN-endangered pinto abalone (Haliotis kamtschatkana), which is confirmed in this area and is subject to harvest as a documented threat. The IUCN-endangered sea otter (Enhydra lutris) uses nearshore kelp habitats in Sitka Sound. The critically endangered sunflower sea star (Pycnopodia helianthoides) formerly dominated rocky intertidal communities here; road development along the Sitka Sound coastline would increase direct access to and disturbance of these intertidal habitats, compounding existing pressures on species already documented at elevated conservation concern.

Potential Effects of Road Construction

Logging Access and Old-Growth Loss Road construction into the Sitka Urban roadless area would enable logging that eliminates the large-diameter conifers, complex canopy, and old-growth floor structures that are irreplaceable on management timescales. For the marbled murrelet and species such as the Alaska holly fern—both dependent on structural conditions that require centuries to develop—old-growth loss from road-enabled logging represents an effectively permanent outcome. Alaska-cedar, already subject to climate-driven decline documented at extreme severity, faces compounded stress when canopy disruption increases soil temperature fluctuations in logged and edge-disturbed stands.

Riparian Degradation in Multiple Drainages Road construction crossing Indian River, Sawmill Creek, Katlian River, or their tributaries would introduce culvert barriers that impede salmon passage and create point sources of sediment discharge at stream crossings. The network character of the Sitka watershed—with multiple named streams draining a shared basin to Sitka Sound—means that road effects introduced in any part of the system propagate downstream to all salmon-bearing reaches. Stream temperature increases from riparian canopy removal affect all downstream reaches, reducing the cold-water conditions that salmon require for egg incubation and juvenile rearing.

Intertidal Disturbance and Abalone Habitat Road construction to the coastline of Sitka Sound would increase foot traffic and vessel access to rocky intertidal zones where pinto abalone occurs. Subsistence harvest of pinto abalone is a documented threat at moderate severity; road access that increases ease of coastal access directly amplifies harvest pressure on a species already at endangered status. The rocky intertidal zone also provides the primary habitat context for sunflower sea star recovery; increased human activity, vessel anchoring, and shoreline modification associated with road development compound the existing challenges of sea star wasting disease recovery.

The Sitka Urban Roadless Area's 112,003 acres lie immediately adjacent to the city of Sitka on Baranof Island, making this one of the most accessible roadless areas in the Tongass National Forest. Five maintained trailheads and two campgrounds—Sawmill Creek and Starrigavan Campground—serve the area, with a network of 20 verified trails providing access to terrain ranging from sea level to alpine ridgelines.

The Indian River Trail (31500) is the most used backcountry route, running 4.2 miles from the Indian River Road End Trailhead through closed-canopy Sitka spruce–hemlock forest along Indian River. The Harbor Mountain–Gavan Hill Trail (31499) is the primary alpine route, covering 4.6 miles from a near-sea-level trailhead to ridge terrain with views of The Sisters and the surrounding island topography. Beaver Lake Trail (31522) reaches Beaver Lake in 1.8 miles, providing access to one of the area's interior lake systems. Mosquito Cove (31673) covers 1.4 miles of coastal forest trail from the Starrigavan trailhead area. The Thimbleberry/Heart Lake Trail (31192) provides a 0.7-mile connection to Heart Lake and Thimbleberry Lake. The Starrigavan Valley Loop system provides approximately 3.5 miles of additional trail through the Starrigavan estuary. The Herring Cove Trail (31525) runs 0.5 miles from the Herring Cove Trailhead. The Salmon Lake/Redoubt Lake Trail (31566) accesses the lake system in 0.3 miles from the Salmon Lake Trailhead.

Birding in this area is among the most productive in southeast Alaska. Twenty eBird hotspots lie within 24 kilometers, with Sitka town leading at 239 confirmed species and 1,399 checklists. The Starrigavan Estuary Recreation Area documents 150 species across 1,132 checklists, with consistent representation of shorebirds, waterfowl, and wading birds in all seasons. Indian River East Tidal Flat contributes 145 species with 249 checklists. The Thimbleberry Trail hotspot registers 66 species with 88 checklists in the forest interior. Confirmed species include marbled murrelet (Brachyramphus marmoratus), trumpeter swan (Cygnus buccinator), humpback whale (Megaptera novaeangliae), bald eagle (Haliaeetus leucocephalus), American dipper (Cinclus mexicanus), varied thrush (Ixoreus naevius), and Townsend's warbler (Setophaga townsendi).

Sport fishing in the Indian River and Sawmill Creek drainages targets pink salmon and chum salmon during their respective summer and fall runs. Coho salmon is confirmed in the system. Both rivers are accessible from the trailhead network—Indian River from the road-end trailhead, and Sawmill Creek from the campground. Belted kingfisher (Megaceryle alcyon) is documented at the estuary and river mouths.

Wildlife observation along the Harbor Mountain–Gavan Hill Trail provides access to mountain goat (Oreamnos americanus) terrain on the upper ridges. Brown bear (Ursus arctos) and mule deer (Odocoileus hemionus) are the most frequently encountered large mammals in the forest interior. Sea otter (Enhydra lutris) is visible from the Mosquito Cove Trail and from the Starrigavan area; harbor seal (Phoca vitulina) hauls out on islets in Sitka Sound adjacent to the coastal trails. Pinto abalone (Haliotis kamtschatkana) occurs in the rocky intertidal zone accessible from coastal trail segments.

Photography opportunities are extensive: the Starrigavan estuary at high tide during shorebird migration, the Indian River corridor during salmon runs when bears and bald eagles concentrate at the streambed, and the alpine terrain of Harbor Mountain–Gavan Hill for mountain goat and landscape photography. The Mosquito Cove Trail and Herring Cove Trail offer coastal forest-to-shoreline subjects within short distances of maintained trailheads.

The recreation value of Sitka Urban depends on the roadless condition. Indian River would lose its salmon runs and bear activity if road crossings introduced sedimentation and passage barriers. The Harbor Mountain–Gavan Hill Trail would lose its backcountry character if road construction extended to the ridge. The Starrigavan estuary's birding quality depends on intact freshwater inputs from the adjacent undeveloped forest—conditions the roadless designation maintains directly adjacent to the city.
