Service Description: Abstract: The Colorado Natural Heritage Program (CNHP) collects data on rare
and imperiled species, subspecies and natural communities (collectively known as Element Occurrences or EOs) in Colorado. Potential Conservation Areas (PCAs) are derived from these data. A PCA represents CNHP's best estimate of the primary area supporting the long-term survival of targeted species, subspecies and natural communities. Purpose: CNHP provides information on the distribution of potential conservation areas in Colorado to public and private agencies and individuals for environmental review, proprietary land management, resource planning, biological and ecological research and general scientific reference.
Supplemental_Information:
Potential Conservation Areas are typically drawn on-screen ("heads up" digitizing) using DOQs or 7.5 minute USGS topographical maps (DRGs) as a reference. Source information is documented in the attribute table. Data are available in geodatabase format or shapefile format. PCAs are land units that have been identified as important to the continued existence of ecological processes that support one or a suite of rare or significant features. Also, a) they are often based on desk-
top scientific references and need ground-truthing; b) they are based
on biological and physical factors and do not account for land owner-
ship and political concerns; c) they are useful for land-use planning and conservation strategies but DO NOT have legal meaning or in any way represent an attempt to regulate or limit the use of private property; and d) they do not automatically exclude any activity what-
so-ever. Instead, they constitute a hypothetical area required to ensure
the continued existence of the targeted elements of biodiversity.
The size and configuration of a PCA will be dictated by the conservation
targets (i.e. those species, communities or systems we seek to
conserve at a given location) and their sustaining ecological
processes. PCA refers to the ability of a conservation area to maintain
healthy, viable targets over the long term (100+ years), including ability to respond to natural or human-caused environmental change.
PCAs do not necessarily preclude human activities, but their ability
to function naturally may be greatly influenced by them. PCAs at all
scales may require ecological management or restoration to maintain
their functionality. CNHP manages data using the Biodiversity Tracking and Conservation System (BIOTICS) which integrates spatial data using ArcView 3.3 (ESRI 1992-2002) with narrative and tabular data using Oracle 10x (Oracle Corporation 1998-2004). BIOTICS was designed by NatureServe,
CNHP's parent organization. To learn more about the BIOTICS data model, refer to http://www.natureserve.org/prodServices/biotics.jsp
