Botanical Report for Herbicide Release for Longleaf Pine Plantations 2013: Sensitive and Conservation Plant Species Winn Ranger District Kisatchie National Forest Southern Region USDA Forest Service Proposed Actions: Herbicide release on 535 acres in 17 separate stands of young longleaf pine trees. Contact Person: David Moore Forest Botanist, Kisatchie National Forest 2500 Shreveport Highway Pineville, LA (318) 473-7016 [email protected] Abstract. The Winn RD is proposing an herbicide release project in 17 longleaf pine plantations encompassing 535 acres. The herbicides proposed for use are triclopyr, imazapyr, and glyphosate. The herbicides will be applied as per label instructions, and by following Forest Service regulations and guidelines. This treatment should kill the competing understory and release the newly-planted longleaf pine trees. This action will also prevent further or future damage to trees after applications have been completed. Surveys were conducted by Moore on September 20, September 21, October 17, October 19, 2012, Nov. 8, 2012, Dec. 6, 2012 and Dec. 12, 2012. No sensitive or conservation plant species were found. No significant populations of non-native invasive species (NNIS) were found. It is expected that none of the 81 sensitive or conservation plant species on the Kisatchie National Forest will occur in the project area, and no trend towards federal listing or a loss of viability is expected to result from the proposed actions. Introduction and Proposed Management Actions This botanical report considers the effects of herbicide release in 17 longleaf pine plantations on the Winn Ranger District, Kisatchie National Forest, Louisiana. Sensitive Plant Species are identified on the USFS Region 8 Intranet, at http://fsweb.r8.fs.fed.us/nr/fwr/PETS_FSWeb/ref/fs/080701_rfss_fsweb.xls. Conservation plant species are identified under the the1999 Revised Land and Resource Management Plan (below called the ―Forest Plan‖) for the Kisatchie National Forest (NF). Moore performed surveys for TESC plant species and their habitats in select stands that comprise the project area (Table 1) on September 20, September 21, October 17, October 19, 2012, Nov. 8, 2012, Dec. 6, 2012 and Dec. 12, 2012. Forest Service direction relevant to this project 1 includes the 1999 Revised Land and Resource Management Plan (Forest Plan) for the Kisatchie NF, the Environmental Impact Statement for the 1999 Revised Land and Resource Management Plan, and Forest Service Manual (FSM) section 2670.32. The Forest Plan has guidelines regarding such habitats as bogs, bayhead swamps, calcareous prairies, calcareous streamside forest, glades, and barrens in Forest Wide (FW) standards and guidelines FW-677 through FW- 700 on pages 2-57 through 2-60.

This botanical report will consider which sensitive or conservation plant species may be present in the project area based on their habitat requirements, which conservation plant species have been found in the project area, and which conservation plant species will be excluded from further consideration based on a lack of appropriate habitat. The effects of the proposed actions on those plant species retained for further consideration will be evaluated and a determination of effects provided. Consultation history No consultation with other agencies occurred with regard to plant surveys because no threatened or endangered plants are known to occur on the Kisatchie NF and the project is occurring exclusively on Forest Service land. Conservation plant species considered and plant species evaluated A. General Considerations 2 The conservation plant species are taken from Table 3-7 of the Final Environmental Impact Statement for the Forest Plan. Not all of the species on this list have suitable habitat within the project area, or they may be found in habitats that may be present, but are prohibited from disturbance under the Forest Plan. With regard to the latter, it is important to note that the Forest Plan prohibits most activities that would disturb the land within 50 feet of a stream (this zone is known as a streamside habitat protection zone or SHPZ), including timber production, regeneration by clearcutting, seed-tree, or shelterwood, salvage of single or double trees, mechanical site preparation, log decks or landings, and extraction of common variety minerals (Forest Wide standards FW-510 and FW-511 on page 2-43 of the Forest Plan. An important consideration for determining which plant species to consider further is their habitat requirements. Plants whose habitats are not found in the project area do not need to be considered further. Different authors have used different terms to describe the same habitats, which can cause confusion. To make the terminology more uniform, the habitat terms used below are taken from the habitat types recognized by the Louisiana Natural Heritage Program, in particular the terms used in their surveys of the Kisatchie National Forest, such as Martin and Smith (1991). Table 2 below indicates which of the species considered were excluded from further analysis and the reasons for their exclusion. In the sections below the effects of the proposed project on the species that were not excluded will be evaluated. Table 2.
