  • Jacob's-Ladder
    Jacob’s-ladder (Polemonium vanbruntiae) Phlox Family (Polemoniaceae) Pennsylvania Endangered Plant Species State Rank: S1 (critically imperiled) Global Rank: G3 (vulnerable) SIGNIFICANCE The Jacob’s-ladder has been given a status of Endangered on the Plants of Special Concern in Pennsylvania list by the Pennsylvania Biological Survey and the Department of Conservation and Natural Resources, based on the relatively few populations that have been documented in the state. It is considered a globally rare species by the Natural Heritage Program. DESCRIPTION The Jacob’s-ladder is a perennial herb to three feet in height. The leaves are alternately arranged and divided into numerous leaflets with entire margins. The individual flowers, appearing in late June and early July, have blue petals and protruding stamens and style. The fruit is a many-seeded capsule. A more common and widespread species, Polemonium reptans, is similar but is smaller in size, has the stamens and style not protruding from the flower, has more of a woodland habitat, and blooms in spring. North American State/Province Conservation Status Map by NatureServe (August 2007) State/Province Status Ranks SX – presumed extirpated SH – possibly extirpated S1 – critically imperiled S2 – imperiled S3 – vulnerable S4 – apparently secure S5 – secure Not ranked/under review HABITAT The species grows in wet soil in woods, thickets and openings. RANGE The Jacob’s-ladder is found in northeastern North America from southern Canada to West Virginia. It is known historically from several widely scattered occurrences in Pennsylvania, although all of the currently known populations are in the northeastern part of the state. REFERENCES .

  • 2021 Targeted Grant Priorities
    2021 Targeted Grant Priorities WRCP is soliciting grant applications for priorities in the following categories – surveys, research, conservation and management and climate change. Detailed priorities within each of these categories are outlined below. It is recommended that projects/grant applications address one of the priorities listed below. However, applications may be accepted that address priorities outlined in the Pennsylvania State Wildlife Action Plan and/or address the needs of plant species or plant communities of concern within the Commonwealth. The applicant should contact the WRCP Agency Coordinator to discuss the project, how it may fit into flora or fauna priorities and potential for funding. Please refer to the “Application Submission Information” section below for further information. Surveys Plant Conservation Genetic Studies Conservation genetic information is a tool for use in plant conservation which can provide a view of how genetically diverse species populations are and inform threatened and endangered plant species recovery plans. DCNR is interested in learning more about the populations genetics of the species listed below. This information will be used by DCNR and the PA Plant Conservation Network in the implementation of species recovery plans and safe-guarding strategies to prevent species extirpation from PA. Aconitum reclinatum, Agalinus auriculata, Carex bicknellii, Euphorbia purpurea, Lycopodiella margueritae, Malaxis bayardii, Paxistima canbyi, Polemonium vanbruntiae, Pycnanthemum torreyi, Trollius laxus, Gaylussacia brachycera For some species, genetic markers may already have been identified by previous studies. Researchers would choose one species from above, or any other highly G-ranked species to focus on, then review published literature to identify species with genetic markers identified.

  • Preliminary List of Species Native Within the Adirondack Park Listed Alphabetically by Common Name and Sorted by Habit V.1 Updated 10.23.2006
    Preliminary List of Species Native Within the Adirondack Park Listed Alphabetically by Common Name and Sorted by Habit v.1 Updated 10.23.2006 Purpose The purpose of this list is to provide an information resource to those wishing to plant or otherwise propagate plants native to the Adirondack Park. It could be used by an individual or a group developing a landscaping plan and wishing to use species native to the Park and a particular county. They could use the list as a source of native species and request nurserymen to provide plant materials from it. Although most of these species are not now available from commercial nurseries, it may be that if continued requests are made for them, the nursery industry would see fit to propagate the desired plants. Requesting and planting natives would reduce the call for non-native and potentially invasive species. It should be noted that some of these species will most likely never be sold commercially because of rarity or difficulty in propagation. The list is meant to being a living document with species added and deleted as additional information is collected and verified. Although it may be tempting, plants should never be harvested from the wild. In fact some of these plants are legally protected, and no harvesting can occur on State lands. Refer to the New York Natural Heritage Program website (http://www.dec.state.ny.us/website/dfwmr/heritage/plants.htm) for a complete treatment of New York State protected plants and federal and State laws regarding rare plants.
