Single-species listings under provisions of the federal Endangered Spe
cies Act (ESA) have caused, or have been accused of causing, significa
nt regional economic impact. in an attempt to avoid such adverse effec
ts on regional economic development, the state of California passed th
e Natural Communities Conservation Planning Act (NCCP) in 1991. It is
a voluntary, consensus-based approach to balancing protection of sensi
tive biota and biodiversity with regional economic development. The pi
lot NCCP program for the conservation of several threatened, endangere
d, and category I species, plus an additional 35 coastal sage scrub-re
lated species in southern California was completed and submitted to th
e public for review and comment in December 1995. This program propose
s the voluntary establishment of a 86,600-ha multispecies reserve syst
em. Once completed, participating landowners will receive ESA Section
10(a) ''incidental take'' permits for present and identified future pr
ojects. Utility rights-of-way are incorporated into the program as imp
ortant connective linkages between reserve units and other adjacent im
portant habitat areas. All data and information regarding the proposed
results of the NCCP are subject to change pending agency response to
public comments on the draft Habitat Conservation Plan and joint EIR/E
IS.
