<br />Hey~ D.L~ and N.S. Philippi, 1999. A Case for Wetland Restoration. New York: John Wiley and

<br />hopeless and cannot sensibly be required, though authors do not argue that complete
<br />restoration is possible. Careful work has created .much better .than nothing" results with
<br />substantial benefits. Also good for background on restoration and wetlands policies, if used
<br />with National Research Council items noted befowJ and special issue on isolated wetlands
<br />from Wetlands: see Nadeau and Leibowitz below.. Book length allows thorough detail of cases

<br />984...1000. This article shows some of what can be done if there ;s interest in regional
<br />conservation planning, for recreational, open spaceJ and amenity values as well as ecological
<br />values. Colorado. according to polls and the Govemorst Commission (see comments by-
<br />Wiener to SWSJ previously mads) show strong public support for these values. If the
<br />leadership seeks to realize those, techniques such as thOse used in Florida are impressive;
<br />see also Theobald 2003, showing work in Colorado with potential applications, and Baron's
<br />book (2001) Hoctor et al. also offer description of some of the rationale for doing plans,

<br />Imporlant point for SWSI that shott-term benefits for some species differ from long-term
