The Biological Assessment serves to: ensure that FS actions do not contribute to loss of viability or trends towards Federal listing for all TES species; comply with requirements of the Endangered Species Act of 1973 (ESA) that actions of Federal agencies not jeopardize the continued existence of listed species or adversely modify critical habitat of listed species; and provide a process and standard by which to ensure that threatened, endangered, proposed, and sensitive species receive full consideration in the decision making process. Consult the Forest Service Manual, Section 2672.4 for a detailed discussion on objectives and standards for Biological Evaluations. This Biological Assessment (BA) considers the potential effects of the Forest Health Project on Threatened, Endangered, and Proposed (TEP) wildlife species. The best available science on TEP wildlife species was used to document this consideration of potential effects, including recent scientific literature, correspondence with knowledgeable individuals in scientific/land management professions, field surveys, and personal observation. Recent scientific literature used in the document is included in the references section. The wildlife and plant species addressed in this document were selected from the Federally Listed Species in Florida from the USFWS (Table 1). Although not federally listed, the Bald Eagle was included in the analysis to communicate compliance with the Bald and Golden Eagle Protection Act. Section 7 contains four listed species that occur in or near the Ocala National Forest (ONF) but were excluded from analysis within the document because the project area does not contain suitable habitat or is outside the known range of the species.

On December 18, 1998, the U.S. Fish and Wildlife Service issued a Biological Opinion on the Revised Land and Resource Management Plan. The Biological Opinion concurred with the Forest Service’s “not likely to affect” determination for 13 federally listed species, and provided terms and conditions for incidental take for five wildlife species that received a “may affect” determination. The Biological Opinion also stated that the “level of anticipated take [was] not likely to result in jeopardy to the species” for the Florida Scrub-Jay, Red-cockaded Woodpecker, Eastern Indigo Snake, Sand Skink, Flatwoods Salamander, and Flatwoods Salamander critical habitat (USDA Forest Service 1999). Issuance of the Biological Opinion concluded all formal consultation on the Revised Land and Resource Management Plan for National Forests in Florida. 3.0 PROPOSED ACTION The Ocala National Forest is proposing to implement the Forest Health Project (see Map 1). The project would thin overstocked pines on approximately 3,700 acres and remove off-site sand pines on approximately 4,500 acres. The proposed actions are described below and evaluated with regard to its potential effects on federally listed species. This project is located within Management Area 7.1 (Longleaf/Slash Pine, Adaptive Management, No RCW Management), Management Area 7.3 (Longleaf/Slash Pine, Adaptive Management, No RCW Management), and Management Area 8.2 (Sand Pine, Mixed Regeneration, Large Openings). Note that changes in the desired condition for MA 8.2 and two guidelines (8.2-5 and 8.2-7) have been implemented under LRMP Amendment #8. Also refer to the Amendment 8 Replacement Pages for the changes to the Desired Future Conditions (available at http://www.fs.usda.gov/detail/florida/landmanagement/?cid=stelprdb5269794). The goals of the Forest Health Project are to improve forest health by improving groundcover conditions, reducing hazardous fuels, and removing off-site canopy species in favor of restoring longleaf pine or oak scrub habitats. Proposed Actions in Detail Thin overstocked pines. 3,696 acres of overstocked stands of slash and loblolly pines would be thinned. Areas may be thinned by removing every other row or every third row in plantation settings, or by crown tree thinning down to a basal area defined by the site index and the age and diameter of the pines on the site. After harvest, sites will be prescribe burned. Sites in need of groundcover restoration will be chopped post- harvest and then be prescribe burned. If southern pine beetle infestation were to occur within these overstocked stands prior to thinning, affected trees and a buffer strip 100’ around the affected area would be felled and removed via commercial harvest. Openings would likely be 2-10 acres in size. If an affected area is impractical to sell commercially due to volume or location, the timber would be felled and not sold. Harvest sand pine by clearcutting. Stands of sand pine would be harvested via clearcut. Post-harvest activities would vary based on the desired future condition for the site: Remove sand pine, plant longleaf pine. On 796 acres of longleaf sites where sand pine has encroached, 3 sites may be prepared with herbicides or mechanical treatment followed by prescribed burning. Longleaf pines will be planted. Hand release treatments may be needed to address continued sand pine seedling encroachment in the future. Remove sand pine, manage as scrub oak. 1,987 acres of scrub sites would be prescribe burned post- harvest, with mechanical treatments (i.e., roller-chopping) possible to facilitate the burn. These sites would be managed as scrub oak, with the scrub in these areas being regularly burned as a portion of a prescribed burn block. Remove sand pine, seed with sand pine. One 234-acre stand would be clear-cut and re-seeded with sand pine. The sand pine in this stand is not off-site, but will be near the other harvest activities in this project. Sites will be prepped for seeding by a roller-chopper and/or prescribed burning. Harvest sand pine by removal cut or remove sand pines by hack and squirt. 1,514 acres of forested stands with significant sand pine encroachment but with potentially unmerchantable volumes of sand pine present would be treated. Forest stands with an operable quantity of merchantable timber would be sold commercially. Stands with a less than operable quantity of merchantable timber would have the sand pine treated by individual stem injection with herbicide. Prescribed burning. Post-harvest prescribed burns are conducted to benefit various TES species by providing effects such as decreasing coarse woody debris and improving germination and resprouting of fire- adapted plant species. The effects of prescribed burning on TES species are also addressed in the Biological Evaluation of the Effects of Prescribed Burning on Proposed, Endangered, Threatened and Sensitive Wildlife Species (USDA 2006). Prescribed burning provides open areas for scrub-jays and mimics the natural effects on plant dynamics that historically came from wildfires. All proposed actions in the current project are consistent with and do not exceed the scope of activities described within the Revised LRMP and subsequent amendments. 4 Map 1. Proposed treatment areas. 5 3.3 Design Criteria Design criteria are included to minimize or eliminate potential negative effects of proposed actions. General measures are listed below as well as specific applicable criteria cited from the Forestwide Standards & Guidelines section of the LRMP. Project-specific criteria are generated for this project or suggest a stricter application of an existing Standard or Guideline. General Measures Incorporate Best Management Practices (State of Florida guidelines) to prevent any adverse effects to water or wetlands. Maximizing the potential for beneficial effects and minimizing the potential for adverse effects on Threatened, Endangered and Sensitive (TES) plant and animal species. Minimizing the potential for introduction and spread of non-native invasive species (NNIS) such as cogon grass, Japanese climbing
