significant portion of their global population. The result was a list of 11 bird species thatfit both criteria (Appendix 2).VertebratesEight vertebrates were selected as primary target species. A total of 365 EOs wereevaluated from which 76 were selected for the Portfolio. Goals were met and exceeded(doubled and quadrupled) for two of the eight vertebrate species; timber rattlesnake andbog turtle. These two species will receive an unnecessarily high level of conservationattention unless these occurrences are removed from the portfolio during the seconditeration. Including marginal EOs makes for an inefficient portfolio. Alternatively, and asmay be the case with the Bog Turtle, we may raise the goal to meet new federal recoveryplan goals. None of the other vertebrate species came close to meeting their goals.Invertebrates57 invertebrate species were chosen as primary target species. A total of 419 EOs wereevaluated from which 213 were selected for the Portfolio. Goals were met for sevenspecies, including dwarf wedgemussel, karner blue butterfly, and ringed boghaunter.Many species did not meet their goals because of a lack of occurrences to choose from inthe database. 15 invertebrate targets had no EOs documented in BCD. Extensiveinventory is required for the majority of invertebrate targets as 50 species (88%) did notmeet their goals.Plants42 plant species were chosen as primary target species. A total of 334 EOs wereevaluated from which 154 were selected for the Portfolio. Goals were met for 10 species,including northeastern bulrush, ram’s-head lady’s-slipper orchid, and Maryland burmarigold.Only two species have distributions that are restricted to this ecoregion;Ogden’s pondweed and basil mountain mint. Neither species met its conservation goaland both require additional inventory.Additional inventory is required for most species but several things need to be kept inmind.. 1) The global rank for an element in many cases reflects the amount of inventorydone for a species or group. Additional inventory for many will undoubtedly lead torevisions to the global rank for the species. Some may drop to G4 or G5 and no longerneed to be part of the portfolio as primary targets. 2) Many species, even with extensiveinventory will not meet their goals because they are naturally rare. This is acceptablewhere it can be shown that there never were sufficient populations to meet the goal.Alternatively, reintroduction and/or the restoration of extant sites with poor currentviability, or introduction at sites with suitable habitat, should be considered.Secondary TargetsThe expert teams selected 14 vertebrate animals, 24 invertebrate animals, and 47 plantspecies as secondary targets. A total of 818 occurrences for 69 secondary targets wereevaluated, of which 241 were captured in Portfolio Sites. Of these, 124 occurrences wereselected as 10-year action occurrences. However, most secondary targets are poorlySPP-RESULTS-2
documented in BCD making analysis very difficult. There were no occurrences in thedatabase for 18 secondary targets.Secondary target occurrences selected for the portfolio were not evenly distributedamong species. 13 secondary target species had no occurrences selected, and 26 specieshad no occurrences identified as 10-year action occurrences. Additionally, 45 secondarytargets had 3 or less occurrences selected for the portfolio, and 56 secondary targets had 3or less occurrences selected as 10-year action occurrences. Some of the secondary targetsrequire interior forest conditions or require large home-ranges, yet only 67 secondarytarget occurrences (for all species) were captured by Tier 1 matrix forest occurrences. Ofthese, only 36 were captured in Tier 1 10-year matrix forest occurrences. Table 3provides a tabular accounting of secondary target element occurrence by portfolio status.Table 3.

This will require inventory and the development of target and stratificationgoals. In the interim, however, we can presume that some undocumented secondarytargets will be captured by other portfolio occurrences.BirdsEleven species of migratory bird were selected as secondary target species. The ExpertTeam believes that Tier 1 Preferred Sites for matrix-forming forest communities willprovide adequate protection for the following forest-dependent bird species:• Black-throated Blue Warbler in northern hardwood forests,• Cerulean Warbler in swamps and bottomlands within matrix sites,• Louisiana Waterthrush in deciduous forests mid-region,• Prothonotary Warbler in larger swamps and bottomlands in the Piedmont,• Wood Thrush in deciduous forests mid-region,• Worm-eating Warbler in deciduous forests midregion.Additional review of Portfolio sites will be required to ensure that an adequate number ofsuitable habitats have been selected regionwide for the remaining five species.• Blue-winged Warbler in wet, old fields and moist, early successional woodlands,• Golden-winged Warbler in old fields, forest openings, and thickets in the Piedmontand NY,SPP-RESULTS-3
