Description:

Abstract:

These matrix occurrences represent the viable matrix forest occurrences in the ecoregion. Tier 1 occurrences are the portfolio matrix occurrences. They represent the best examples of viable matrix forest and encompass at least 1 representative of each matrix Ecological Land Unit (ELU) group. Tier 2 occurrences are also viable matrix occurrences, but are not needed to meet representation goals for the portfolio. Tier 2 occurrences represent the alternate portfolio. Matrix occurrences are bounded by fragmenting features such as roads, railroads, major utility lines, and major shorelines. The bounding block feature types were chosen due to their ecological impact on biodiversity in terms of fragmentation, dispersion, edge-effects, and invasion of alien species.

Purpose:

Matrix sites are large contiguous areas whose size and natural condition allow for the maintenance of ecological processes, viable occurrences of matrix forest communities, embedded large and small patch communities, and embedded species populations. The goal of the matrix forest selection was to identify viable examples of the dominant forest types that, if protected and allowed to regain their natural condition, would serve as critical source areas for all species requiring interior forest conditions or associated with the dominant forest types.

Type_of_Source_Media: CD-ROM

Source_Contribution:

The original source linework for the transportation network in the U.S. came from 1:100,000 scale Macon USA TIGER 94 data and GDT Major Roads from ESRI Data and Maps 1999 which were processed to create the block coverage (see block coverage for more details on processing). In Canada the bounding features used came from ESRI Data and Maps 2003 and a variety of provincial data sources at multiple scales.
