Abstract:
A Network of Conservation Areas (NCA) will fit one of the following
definitions:
A. A landscape area that encompasses Potential Conservation Areas (PCAs)
that share similar species or natural communities and ecological
processes. NCAs include unoccupied or unsurveyed areas that are
within the same ecological system that the species or natural
communities require. NCAs contain PCAs with an obvious repeating
pattern (that is, the same species or natural communities are in
each associated PCA).
B. A mostly intact, lightly fragmented landscape that supports wide-
ranging species and large scale disturbances. NCAs include
unoccupied or unsurveyed areas that demonstrate the connectivity of
the landscape. NCAs contain PCAs that may occur at a variety of
ecological scales.
Purpose:
CNHP provides information on the distribution of Network of 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:
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
natural communities. NCAs are derived from PCAs and are designed to
reflect large, intact landscapes or areas with an obvious repeating
pattern for large-scale planning.
Networks of Conservation Areas typically are drawn onto 1:100,000 or
1:250,000 scale USGS topographical maps and digitized using Arc/Info
7.2.1 on a UNIX platform OR drawn on-screen ("heads up" digitizing) by
CNHP staff in ArcView using 1:100,000 or 1:250,000 USGS digital raster
graphics (DRGs) as a reference. Source information is documented in
the attribute table. Data are available in Arc/Info export format
(subclass ncas) and ArcView shapefile format; feature class is regions
or multi-part shapes. Note attributes for the NCA regions coverage are
stored in .patncas.
CNHP manages data using the Biodiversity Tracking and Conservation
System (BIOTICS) which integrates spatial data using ArcView 3.2a
(ESRI 1992-2000) with narrative and tabular data using Oracle 9i
(Oracle Corporation 1994-2002). BIOTICS was designed by NatureServe,
CNHP's parent organization. To learn more about the BIOTICS data model,

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All items were checked for invalid or null values in GIS and
found to be satisfactory. An assessment of the accuracy of
attributes captured in the field by the observer has not been
completed.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: Unknown
Attribute_Accuracy_Explanation:
Attribute accuracy is dependent on the expertise of the
field biologist.
Logical_Consistency_Report:
Arc/Info export coverage was found to be topologically correct
in Arc/Info Workstation 9.0 SP3. Data were imported from an
ArcView shapefile and cleaned (dangle length and fuzzy tolerance
set to .1m). No node, label or region errors are present. ArcView
shapefiles do not have topology.
Completeness_Report:
NCAs are only designed for PCAs that are derived from elements
tracked by CNHP. Refer to http://www.cnhp.colostate.edu/list.html
for an up-to-date list of tracked elements. While we strive to
have the most comprehensive database of significant Networks of
Conservation Areas, data are incomplete at this time.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
NCAs are typically mapped onto 1:100,000 scale or 1:250,000 scale
USGS topographical maps (digital or hard copy). Refer to attribute
information for source data and scale.
Vertical_Positional_Accuracy:
Elevation is collected in the field by biologists so this is
dependent on the estimate of natural resource professionals.
Process_Step:
1) Element Occurrence data are collected in the field by CNHP biologists
or other experts.
2) Data are digitized and transcribed in BIOTICS by CNHP information
managers.
3) CNHP biologists digitize Potential Conservation Areas in ArcView 3x
based on the locations and quality of Element Occurrences and the
natural processes needed to sustain them.
4) PCAs are imported to BIOTICS and transcribed.
5) PCA boundaries and transcription are quality controlled by CNHP
information managers and the GIS Coordinator.
6) NCAs are designed from PCAs by CNHP biologists, where applicable
(i.e. intact landscapes or repeating patterns exist. Not all PCAs
have associated NCAs.)
7) NCAs are imported to BIOTICS and transcribed.
8) NCA boundaries and transcription are quality controlled by CNHP
information managers and the GIS Coordinator.
9) Prior to export, data integrity scripts are run to ensure spatial
and narrative information are synchronized.
10) Oracle attributes are joined to the NCA shapefile.
11) Attributes are quality controlled in GIS for invalid or null values.
If an Arc/Info coverage is requested:
12) NCA shapefile is converted to an Arc/Info regions coverage, subclass
ncas, with double precision using Arc/Info WorkStation 9.0 SP3.
13) Coverage is cleaned with fuzzy tolerance and dangle length set to .1m.
14) Labels are created and idedit is run to update user-ids.
15) Coverage is checked for node errors, label errors and region errors.
16) Project define is used to set projection parameters.
17) Export cover is used to create Arc/Info export file (.e00)

Steps one through 8 are continual. Steps 9-17 are completed on the
