SCOPING LETTER

NORTHERN TONGASS INTEGRATED WEED MANAGEMENT PLAN

U.S. FOREST SERVICE

TONGASS NATIONAL FOREST

HOONAH, JUNEAU, SITKA AND YAKUTAT RANGER DISTRICTS AND 

ADMIRALTY NATIONAL MONUMENT

INTRODUCTION

The Forest Service has prepared this scoping letter to inform the public about the project proposal for the 

Northern Tongass Integrated Weed Management Plan. The objective (purpose) of the project is to 

eradicate, control, or contain invasive and other non-native plants (“weeds”) within the Hoonah, Juneau, 

Sitka and Yakutat Districts and Admiralty National Monument (Figure 1). 

In July 2015, five open houses for this project were held in Yakutat, Juneau, Angoon, Hoonah and Sitka. 

Based on public input at these meetings the following preliminary issues were identified: 

 Herbicide toxicology/herbicide use 

 Herbicide impacts on non-target vegetation 

We would like to receive additional public input based on the Need for the Proposal (Need), the Project 

Objectives (Purpose) and Proposed Action presented below. Your input will help us identify any 

additional concerns or issues related to this project, refine the proposed action, and to develop additional 

alternatives to the proposed action. See below for how you can submit your comments. 

EXISTING CONDITION

Field inventories on Forest Service lands have identified 138 different weeds, both invasive and other 

non-native plant species, approximately 2,800 acres of infestation within the boundaries of the 8 millionacre project area (Hoonah, Juneau, Sitka and Yakutat Districts and Admiralty National Monument). 

Fourteen of these weed species, totaling approximately 60 acres, are target weeds, meaning they are the 

species of greatest concern (Table 1). Included on the target weed list are bull thistle, field mustard, reed 

canarygrass, Canada thistle, Japanese and Bohemian knotweeds, orange hawkweed, oxeye daisy, Scotch 

broom garlic mustard, and ornamental jewelweed, among others. 

Undeveloped lands within the project area have relatively few weeds. Known infestations are primarily in 

areas that receive high use, such as along roads, recreation sites, some riparian areas and cabin sites. 

Alaska has been relatively insulated from the introduction and subsequent problems that have impacted 

other states. This is due in part to its remoteness and low population. That said, existing infestations of 

weeds are spreading and new introductions are increasingly being discovered.

PROJECT AREA

In addition to the five Tongass management units (Hoonah, Juneau, Sitka and Yakutat Districts and 

Admiralty National Monument), the Northern Tongass Integrated Weed Management Plan project area 

includes non-National Forest System (non-NFS) lands adjacent to these districts. Non-NFS lands have 

been included in the analysis for a couple reasons. 

1. Including all lands provides a better overall picture of the problem - what weed species are out 

there and where they are located?

2. Weeds can spread rapidly across the landscape to all land ownerships. By including non-NFS 

lands in the analysis, the Forest Service is better prepared to manage weeds regardless of 

ownership, provided other land owners are interested in partnership opportunities with the Forest 

Service if federal funds become available for such projects. 

NEED FOR THE PROPOSAL

Invasive plants displace native plant communities and cause long-lasting economic and ecological 

problems within and outside the National Forest and are defined as “nonnative plants whose introduction 

does or is likely to cause economic or environmental harm or harm to human health” [Executive Order 

13112]. 

1. Invasive plants can degrade fish and wildlife habitat, out-compete native plants, impair water 

quality and watershed health, and adversely affect a wide variety of other resource values such as 

scenic beauty and recreational opportunities; 

2. Invasive plants can spread rapidly across the landscape to all land ownerships; 

3. Invasive plant infestations in the project area are relatively small and predominately concentrated 

near developed areas, such as, along roadsides and at administrative sites, rock pits and recreation 

areas which provides an opportunity for the Forest Service to be proactive and minimize adverse 

impacts while still in the early stages of invasion; and 

4. Early-stage invasive plant treatments include reduced treatment costs, greater effectiveness of 

treatment methods, less chemical use, and less ground and habitat disturbance. 

PROJECT OBJECTIVES (PURPOSE) 

The purpose of the Northern Tongass Integrated Weed Management Plan is to: 

1. Eradicate or control known weed infestations and treat new infestations, when detected, in an 

efficient and cost-effective manner that complies with environmental standards. This would move 

us toward the desired future condition stated in the Tongass National Forest Land and Resource 

Management Plan (2008) on p.2-1, “Viable populations of native and desired nonnative species 

and their habitat are maintained and are not threatened by invasive species....” 

2. Address Forest Plan Goals and Objectives, Biodiversity Goal (p. 2-4), “Maintain ecosystems 

capable of supporting the full range of native and desired nonnative species and ecological 

processes. Maintain a mix of representative habitats at different spatial and temporal scales.” 

Objective (c), “Manage the Forest in order to reduce, minimize, or eliminate the potential for 

introduction, establishment, spread, and impact of invasive species.” 

3. Maintain Wilderness quality objectives as per the Forest Plan, Wilderness Goal (p. 2-8), “Manage 

designated Wilderness to maintain an enduring wilderness resource while providing for the public 

purposes of recreational, scenic, scientific, educational, conservation, and historical use, as 

provided in the Wilderness Act of 1964 and ANILCA” and Wilderness Objective, “Preserve and 

perpetuate biodiversity. Inventory and reduce or eliminate invasive species in Wilderness.”

PROPOSED ACTION

The proposed action would use integrated pest management including manual treatments (e.g., hand 

pulling and tarping), mechanical treatments (torching, and mowing), and herbicides (spot and broadcast 

spraying) to eradicate, control, or contain populations of weeds on the Hoonah, Juneau, Sitka and Yakutat 

Districts and Admiralty National Monument of the Tongass National Forest. The Forest Service is 

including non-National Forest System Lands in the analysis area to allow for a comprehensive approach 

to weed management, and enable future partnerships with other landowners if funding becomes available 

to local communities through federal grants or other initiatives. 

A treatment “cap” of 800 acres per year is proposed. The acreage cap is not a target. It is part of the 

project design to limit treatment acres, while allowing for flexibility when faced with unpredictable yearly 

funding levels, treatment of currently unidentified infestations using the adaptive management tool Early 

Detection Rapid Response (EDRR), and ongoing treatments. Newly infested acres, as well as re-treated 

acres (typically successful treatment of infestations takes a minimum of 2 years) would be counted 

annually. 

Prioritization of treatment is proposed to occur annually using a decision framework that provides a 

consistent process to determine target weeds for treatment and treatment methods. The target weeds are 

the focus of this project since they have been determined to pose a threat to the ecological integrity or 

desired condition of the sites they occupy (Table 1). Species on the non-target weed list would not be 

targeted specifically, but incidentally when adjacent to target species or present in sensitive areas (to see a 

table of these species go to the project page at http://www.fs.usda.gov/project/?project=49999). For 

example, non-target species (e.g., clover or common plantain) may only be treated in sensitive areas such 

as wilderness. Alternatively, target species (e.g., reed canarygrass or orange hawkweed) may be treated 

while its population is small and manageable in a riparian area, but may be tolerated as a large infestation 

along a roadside and not treated at all. This flexibility is anticipated to help effectively evaluate the 

priorities of managing any weed plant population within the project area. 

To evaluate the effects of the proposed action on the natural resources within the project area, weed data 

(species, location, extent) is organized by 6th Level Hydrologic Units (HUCs) (see Figure 2). At the HUC 

(i.e., watershed) scale, site types have been identified. Site types represent where most known infestations 

occur, and are typically high-use areas where future infestations are expected (i.e., along roadsides, 

recreation areas, rock pits, etc.) and are likely locations for vectors to pick up seeds or propagules for 

transport to other high-use areas.
