` - <br />� <br />r� <br />\� <br />4.0 IMPACT ASSESSMENT <br />� <br />' <br />4.1 Determination of Acreage of Potential Scrub -Jay Habitat to be Impacted, <br />_ <br />Preserved and Restored <br />. ` 41.1 &8e1bO1&�l�y <br />Habitat Studies' <br />' <br />� High resolution digital onhnpbnm quads (DOUa) were obtained for the HCP Plan Area <br />to display required data. The DDUm are available anmyu u wide area and provide <br />consistent, convenient, high quality templates for managing and displaying spatial <br />data using readily available software (e.g. A,uVinvx ARC/INFO) on most hardware <br />� - <br />platforms, using Windows 95 or Unix operating systems (Breininger and Oddy 1998), <br />. <br />The D0Uowere used in this analysis auo template tnview the spatial boodon of tile <br />ITP impact area, Scrub -Jay Habitat Compensation Areas, and core areas o/the South <br />_ <br />Brevard County/North Indian River County mompopu|adon, arid to assign specific <br />� <br />habitat and demographic attributes with d|gio`| phqtogmphy as o Uaoxground <br />. <br />Imagery from 1943' 1957, and 18O5were obtained mquo|imbvehdocoribo habitat <br />changes over time for pomoano of assessing the potential for habitat restoration to <br />provide opdmvlooruh,jay habitat conditions. As illustrated by Figure 2, use of D0Up <br />is valuable in this study as they clearly ,oveo| the predominant land use within thu <br />^ , <br />HCP Plan Area. <br />� <br />Habitat polygons were digitized for each of the Scrub -Jay Habitat Compensation <br />Areas inARC/INFO coverage and include the following attributes: acreage of habitat <br />_ <br />polygons, habitat typo' potential for restoration as °cruh-jay habitat, soil moisture <br />condition (xeric, maoio' or *md. need for pine thinning, shrub height dauo (o <br />measurement of habitat gou|iry), and occupation by ac/ub-jays. DoOn|bun of these <br />`~ <br />attributes for each polygon provided a mechanism to evaluate Lho regulatory <br />. <br />compliance of this HCP and todetermine the, habitat restoration/management needs <br />for each site. Field surveys were conducted in the summer/fall of 1898 to review tha <br />~~ <br />mapped polygons for accuracy with regard to habitat composition and structure and <br />potential for habitat ,o��o,a/ivn �u provide npdme| worub�ay habitat conditions. <br />l� ' <br />` Additionu|muwavo were conducted xteach compensation area toUp-date the number <br />_ <br />and extent ofscrub jay territories occupying these sites, <br />r <br />�~ <br />The mapped habitat /mkg000 are presented for each Scrub -Jay Habitat <br />� <br />Compensation Amoo in the Fiyomo 4` G' arid 8 with the digital photography as o <br />^ <br />background, #gv,ox 5, 7, and 3 provide the corresponding habitat polygons <br />~. uoqumnhrUy numbered for idonU|inobn, and evaluation.
