NOTICE: The project that is the subject of this report was approved by the Governing Board of the
National Research Council, whose members are drawn from the councils of the National Academy
of Sciences, the National Academy of Engineering, and the Institute of Medicine. The members of
the committee responsible for the report were chosen for their special competencies and with regard
Or appropriate balance.
This report has been reviewed by a group other than the authors according to procedures ap-
proved by a Report Review Committee consisting of members of the National Academy of Sciences,
the National Academy of Engineering, and the Institute of Medicine.
The National Academy of Sciences is a private, non-profit, self-perpetuating society of distin-
guished scholars engaged in scientific and engineering research, dedicated to the furtherance of
science and technology and to their use for the general welfare. Upon the authority of the charter
granted to it by tile Congress in 1863, the Academy has a mandate that requires it to advise the
federal government on scientific and technical matters. Dr. Frank Press is president of the National
Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National
Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its
administration and in the selection of its members, sharing with the National Academy of Sciences
the responsibility for advising the federal government. The National Academy of Engineering also
sponsors engineering programs aimed at meeting national needs, encourages education and research,
and recognizes the superior achievements of engineers. Dr. Robert M. White is president of the
National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure
the services of eminent members of appropriate professions in the examination of policy matters
pertaining to the health of the public. The Institute acts under the responsibility given to the Nation-
al Academy of Sciences by its congressional charter to be an adviser to the federal government and,
upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I.
Shine is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to
associate the broad community of science and technology with the Academy's purposes of furthering
knowledge and advising the federal government. Functioning in accordance with general policies
determined by the Academy, the Council has become the principal operating agency of both the
National Academy of Sciences and He National Academy of Engineering in providing services to
the government, the public, and the scientific and engineering communities. The Council is adminis-
tered jointly by both Academies and the Institute of Medicine. Dr. Frank Press and Dr. Robert M.
White are chairman and vice chairman, respectively, of the blational Research Council.

Preface
The Committee on Scientific and Technical Criteria for Federal Acqui-
sition of Lands for Conservation was formed under the auspices of the
Board on Environmental Studies and Toxicology of the National Re-
search Council's Commission on Life Sciences. Our charge was to
review Me criteria and procedures under which land is acquired for
conservation by four of the federal land-management agencies the
National Park Service, the U.S. Forest Service, the U.S. Fish and
Wildlife Service, and the Bureau of Land Management.
The subject is one of great complexity, and we saw disorder wherever
we looked-in the definitions of criteria, procedures, and acquisition; in
the histories, laws, and practices of the agencies; in the role of Congress;
in the elaboration of the details of the acquisition transactions; in the
difficulties of identifying who owns what in a world of partial and over-
lapping entitlements; in the methodologies used to describe, evaluate, and
compare possible acquisitions; and in the mysteries of the social and
natural sciences that stand in the way of firm predictions of whether
acquisition X will achieve goal Y.
The field is so topsy-turvy that many of its most cherished assump-
tions must be set aside. Doubt now assails the scientific assumptions that
conservation goals can be achieved indefinitely by property set-asides in
the form of parks, preserves, and "arks." And questions arise on the
policy front of whether land-acquisition goals can be realized by contin-
ued heavy reliance upon He crude too] of full-fee acquisition.
Land acquisition by government agencies raises a host of sociological,
lox
OCR for page R10
and inevitably political, issues of intense interest to numerous people-
inholders, land-rights groups, acquisitions intermediaries, conservation
organizations, state and local governments, and others. Indeed, the
ultimate question of whether acquisition A should be given a higher
priority than acquisition B is a political issue, because it boils down to
a comparison of incommensurate values. The committee attempted to
steer clear of this political thicket, and focus on description of the com-
plex acquisition systems and on the technical and scientific aspects of the
criteria. Congress makes political choices and exercises a strongly inde-
pendent role in acquisitions, as the committee description shows. The
chapter on the social effects of land acquisition illustrates, however, that
topics of intense political controversy are not immune from illumination
by scientific method.
The recommendations of this report can be described in large measure
under the heading of "making connections" and improving integration.
These include the recommendations to broaden the acquisition analysis
from the single parcel to the landscape context; to link up piecemeal
purchases to longer-term acquisition plans; to widen the scope of the
acquisition techniques; to think in terms of corridors, connections, and
linkages between properties, to identify holdings of other agencies and
gaps in systems of protective ownership; and to sharpen the tools of ac-
quisition to respond to emergent and opportunistic circumstance.
My personal appreciation is extended to the committee members who
undertook the task with collegial enthusiasm and scientific objectivity.
Their collective knowledge and experience cutting across many disci-
plines will be apparent to the readers of the report. The committee was
guided and assisted in indispensable ways by the staff of the National
Research Council. Sylvia Tognetti, project director until July 1992, was
our bulldog, who did many of the basic research, writing, and coordina-
tion activities. David Policansky, program director, provided us guid-
ance, perspective, and He judgmental interventions of the expert on
science policy that he is. Lee Paulson, project director since July 1992,
gave us He substantial editorial assistance that we needed and a welcome
input of energy to carry us over He last hurdles to publication.
~ would like to thank the individuals who made presentations to the
committee and who provided us with statements and data. They include
Henry Diamond, David Gibbons, Chip Collins, Matt Connolly, lack
Walter, Robert I. Smith, David Ford, John Heisenbuttel, Dean Bibles,
Richard Moore, Michael Scott, Jerry Sutherland, Joseph Wrabek, Dale
Crane, Bob Like, Chuck Williams, and Charles Jordan. We are grateful
