This Conservation Strategy provides a cohesive umbrella for all signatories to operate under and reference but each signatory has their own legal process and authority to implement the Strategy. This Conservation Strategy would remain in effect beyond recovery, delisting, and the five year Monitoring period required by the Endangered Species Act (ESA). The agencies are committed to be responsive to the needs of the grizzly bear through adaptive management actions based on the results of detailed annual population and habitat monitoring. The purposes of this Conservation Strategy are to: − Describe and summarize the coordinated strategies, standards, and guidelines developed for managing the grizzly bear population, grizzly bear/human conflicts, and grizzly bear habitat to ensure their continued conservation in the NCDE. − Document the regulatory mechanisms, legal authorities, policies, management documents, and monitoring programs that will maintain the recovered grizzly bear population. − Document the commitments agreed to by the participating agencies. Within the NCDE, the grizzly bear population and its habitat will be managed using an approach that identifies a Primary Conservation Area (PCA) and three additional management zones (Zone 1, Zone 2, and Zone 3: see Figure 1). The PCA is the area currently known as the NCDE Grizzly Bear Recovery Zone. This is where the most conservative habitat protections would remain, with habitat conditions that were compatible with the increasing grizzly bear population from 2004‐2011 being maintained. Grizzly bears are also expected to occupy habitat outside the PCA in Zones 1 and 2 where they may serve as a source population to other grizzly bear ecosystems in the lower 48 States. Habitat and population protections would vary by management objective in these Zones with more protections in areas identified as “Demographic Connectivity Areas.” While Management Zone 3 primarily consists of areas where grizzly bears do not have enough suitable habitat to support population growth, they were included in this Conservation Strategy because a bear living in Zone 3 most likely originated from the NCDE population. Grizzly bear occupancy will not be actively discouraged in Zone 3 and the management emphasis will be on conflict response. Relationship to Other Plans By integrating the Montana state plan into the Strategy, it was ensured that this plan and the Strategy are consistent and complementary. The state plan is formally incorporated in the Conservation Strategy as an Appendix. Relationships with national forest and national park plans are also mentioned throughout the Strategy. Our intent is to have signatories of this Conservation Strategy representing the ii NCDE Grizzly Bear Conservation Strategy April 2013 land management agencies incorporate the habitat standards and guidelines described in this Conservation Strategy into their respective management plans. CHAPTER 2 – DEMOGRAPHIC CRITERIA To maintain a healthy (recovered) grizzly bear population in the NCDE, it is necessary to have adequate numbers of bears that are well distributed with a balance between reproduction and mortality. This section details the demographic criteria necessary to maintain and enhance a recovered grizzly bear population in the NCDE. The standards and monitoring protocol focus on the Recovery Zone and the area immediately around it identified in this Conservation Strategy as the NCDE Primary Conservation Area (PCA) and Management Zone 1 (Zone 1) respectively. Because grizzly bears are a difficult species to monitor, multiple criteria are identified to provide sufficient information upon which to base management decisions. This Conservation Strategy sets an objective of maintaining a recovered grizzly bear population in the NCDE area sufficient to maintain a healthy population in biologically suitable habitats within the PCA and Zone 1. This Conservation Strategy sets both demographic goals, which may be difficult to quantify and demographic standards, which are objective and measurable criteria of population status and health. It is the goal of the agencies implementing this Conservation Strategy to maintain a genetically diverse NCDE grizzly bear population with at least 800 grizzly bears. We will achieve this goal by including specific standards to document a widely distributed population, a high adult female survival rate, and sustainable mortality limits that will not result in long‐term population decline. CHAPTER 3 – HABITAT MANAGEMENT AND MONITORING The goal of habitat management on public lands is to maintain conditions compatible with a stable to increasing grizzly bear population in the NCDE. This Conservation Strategy identifies a Primary Conservation Area (PCA) and three additional management zones (Zone 1, Zone 2, and Zone 3: see Figure 1), each with varying levels of habitat protections depending

It is endemic to West Java, Indonesia, specifically around Mount Gede, Mount Pangaro and south of Sukabumi. The Bleeding Toad’s scientific name, cruentata, is from the Latin word meaning “bleeding” because of the frog’s overall reddish-purple appearance and blood-red and yellow marbling on its back. Geographical range The population declined drastically after the eruption of Mount Galunggung in 1987. It is Knowledge believed that other declining factors may be habitat alteration, loss, and fragmentation. Experts Although the lethal chytrid fungus, responsible for devastating declines (and possible Get Involved extinctions) in amphibian populations globally, has not been recorded in this area, the sudden decline in a creekside population is reminiscent of declines in similar amphibian species due to the presence of this pathogen. Only one individual Bleeding Toad was sighted from 1990 to 2003. Part of the range of Bleeding Toad is located in Gunung Gede Pangrango National Park. Future conservation actions should include population surveys and possible captive breeding plans. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership.

Historically,one of the most successfulprograms was the reintroductionof 254 Americanblack bears (Ursus americanus) from Minnesotato the InteriorHighlands of Arkansasin the 1960s; that populationhas grown to >2,500 today. More recent efforts have involved fewer but bettermonitored animals and have sometimes employed techniquesto improve site fidelity and survival. In Pennsylvania,for example, pregnantfemale Americanblack bears were successfully translocatedfrom winterdens, the premisebeing thatthe adultfemales would be less likely to returnbecause of the presenceof young cubs. That winter-releasetechnique was comparedto summertrapping and release in Tennessee;winter releases resultedin greatersurvival and reducedpost-release movements.

Lance Craighead, Mike Bader; grizzly bears: National Digital Library; landscape: Keith J. Hammer. Design and layout: Dawn Serra Foreword his compilation of statements from leading grizzly bear and conserva- tion scientists represent a cumulative body of knowledge and experience coveringT more than 200 years. They convey information that is essential for the survival and biological recovery of the grizzly bear in the Rocky Moun- tains. This includes the conservation genetics, population viability, habitat dynamics and security, food habits, bear-human interactions and total spatial requirements in a meta-population context. Grizzly bear management in the Rocky Mountains has long been an exercise in political appeasement of economic interests. The best available scientific information is ignored or cited out of context to suit management prerogatives. Agency scientists and decision-makers are now shackled by an unprecedented exploitative agenda. In his 1996 award acceptance speech before The Wildlife Society, legendary grizzly bear scientist Dr. John J. Craighead said: “To preserve the grizzly bear in its natural state, we must keep intact the entire spectrum of biodiversity present within its public-land habitat in the Northern Rockies.

  • Testimony Regarding H.R. 2532 (Tribal Heritage and Grizzly Bear Protection Act) Before the U.S. House of Representatives Committ
    Testimony Regarding H.R. 2532 (Tribal Heritage and Grizzly Bear Protection Act) Before the U.S. House of Representatives Committee on Natural Resources Subcommittee on Water, Oceans, and Wildlife Jonathan Wood Senior Attorney, Pacific Legal Foundation Research Fellow, Property and Environment Research Center May 15, 2019 Main Points ● The Greater Yellowstone ecosystem grizzly’s recovery is due to the collaboration of federal biologists, states, tribes, conservation groups, and landowners. ● Congress should encourage these efforts to continue while preserving the flexibility states and tribes need to manage growing grizzly populations. ● Unfortunately, H.R. 2532 could discourage further recovery efforts for this species and potentially others. ● Instead, Congress should incentivize continued state and tribal efforts to establish additional populations. ● It should also seek to convert grizzlies into less of a liability and more of an asset for the landowners who accommodate them or provide habitat. ● Ultimately, managing recovered wildlife is a state responsibility, and it’s time for states to lead on grizzly bear conservation. U.S. House of Representatives May 15, 2019 Page 1 Chairman Huffman, Ranking Member McClintock, and honorable members of the subcommittee, thank you for inviting me to address this important topic. I am a senior attorney with Pacific Legal Foundation, where I litigate environmental cases, principally concerning endangered species. I am also a research fellow with the Property and Environment Research Center based in Bozeman, Montana, where they directly experience the costs and benefits of grizzlies. I’ve also written extensively on endangered species and other environmental issues, including in law review journals and articles for the popular press.

  • Ursus Americanus American Black Bear Least Concern
    Ursus americanus American Black Bear Least Concern Geographic Range Information American black bears are found through much of Canada, the United States, and the northern half of Mexico. Although they were extirpated from large portions of their historic range because of habitat loss and (mainly intentional) overexploitation, their occupied range has been expanding in recent years (Pelton et al. 1999, Williamson 2002). The species has, nevertheless been extirpated from large parts of its former range, especially in the Midwest of the United States, and in Mexico. American black bears presently occupy all provinces and territories of Canada, except Prince Edward Island (where they were extirpated in 1937), 41 U.S. states (with occasional sightings in at least 3 others), and 8 states of northern Mexico. The species never existed outside of these three countries. Range Countries Canada Mexico United States 2 Population Information During the past two decades, most American black bear populations have grown both numerically and geographically (Williamson 2002). Sixty percent of U.S. and Canadian states and provinces report increasing populations, and all other populations appear to be either stable or fluctuating with no clear trend (Garshelis and Hristienko 2006). Based on 3 sums of estimates for individual states, the total U.S. population, excluding Alaska, is estimated at somewhat greater than 300,000. No reliable estimate exists for numbers of black bears in Alaska, although most authorities presume there to be 100,000–200,000 animals. Similarly, large populations in some parts of Canada are not reliably known, but countrywide estimates center around 450,000 (principally in British Columbia, Ontario, and Québec).

  • Brown Bear (Ursus Arctos)
    Brown Bear (Ursus arctos) Brown Bear (Ursus arctos) Isolated Subpopulations Because the conglomerate Brown Bear population is large and spread over portions of three continents, globally they are Least Concern. However, there are many small, isolated populations that are threatened. Some, such as the Brown Bears of the Gobi Desert in Mongolia, are genetically isolated and ecologically unique so their status is of great concern. Other populations are demographically separated from the large, continental populations (spanning across Alaska, Canada, and Russia) by a very short distance and, although they can usually be distinguished by their genotypes, are genetically and ecologically similar to adjacent populations (Proctor et al. 2012). Here we apply IUCN Red List Criteria for isolated populations of Brown Bears (see Table 1) following the guidance of Gärdenfors et al. (2001) and IUCN (2012). In some cases these assessments have been adjusted by one category, as suggested by Gärdenfors et al. (2001) and IUCN (2012): "If the taxon is endemic to the region or the regional population is isolated, the Red List Category defined by the criteria should be adopted unaltered. If, on the other hand, conspecific populations outside the region are judged to affect the regional extinction risk, the regional Red List Category should be changed to a more appropriate level that reflects the extinction risk as defined by criterion E (IUCN 2001, 2012). In most cases, this will mean downlisting the category obtained in step two, because populations within the region may experience a rescue effect from populations outside the region”. Following this directive, we made these adjustments based on 3 criteria: 1.
