historically <strong>and</strong> it is not found elsewhere on this<br />
type of gently sloping habitat.<br />
4. Validate recovery objectives<br />
Too little is presently known about the demography <strong>and</strong> life<br />
history of these two species to permit evaluation of population<br />
stability, <strong>and</strong> to verify the scientific validity of the stated<br />
recovery objectives in this plan. In the course of securing <strong>and</strong><br />
augmenting these populations, field studies should be supported<br />
<strong>and</strong> data used to devise Population Viability Analysis (PVA)<br />
models.<br />
41. Conduct basic demographic <strong>and</strong> life history studies<br />
Data on demography <strong>and</strong> life history should be collected from<br />
the existing wild populations <strong>and</strong> from any newly established<br />
colonies.<br />
42. Determine the number of populations needed to ensure<br />
long- term survival<br />
It is necessary to know whether or not establishment of six<br />
populations is adequate to safeguard against catastrophic<br />
events over the next 200 years.<br />
43. Determine the number of individuals needed to ensure<br />
the lone-term survival of each population<br />
It is necessary to determine the number of individuals<br />
needed to ensure the long-term survival of each population.<br />
