Evaluation and Assessment for Conservation-1

Summary / Draft

1.6 Evaluation and Assessment
1.6.1 Land evaluation
Purpose for evaluation: A process whereby the potential use ;
Suitability of the land for various purposes; Alternatives uses are
assessed on the basis of certain criteria
1.6.2 ______________
客觀/ 主觀的指標：
Objective:
ex. Species richness→ alongside subjective value judgment
Isn’t everything to show the worth of Nature reserve/ National
Park/ land

1.6.3 ______________
u Determine priority for conservation
n Need to  identify conservation needs; ‚ prioritize those needs
n “Because the world stand to lose a higher proportion of large
vertebrates then of other taxa, some disproportionate expenditure on
their conservation is justified?
n Ex-situ / In-situ conservation problems: (the importance of priority)
Ex-situ: planning part
In-situ: resource and finance are limited
n Reid and Miller’s (1989) conservation priorities:
Distinctiveness 代表性/ 區別性; Utility 效能; Threat 威脅

相關criteria 設定可能出現的問題
If single species are the target of conservation effort, then what are
the best criteria for the selection of those species? (關鍵物種的選擇)

Saving the last fragments of nature sometimes require a choice to be
made the choice can base on any taxonomic/ ecological criteria as
well as utilitarian (功利) & intrinsic (國有) feature. (維持某些地景的
代表性)

Overall aim to “maximize biodiversity” wherever possible? Is it
better to “combine utilitarian & conservation interests”. (連結一些
利益以維持最大的生物多樣性是否可行)

There should be established criteria for selection of PA or not? (保護
區選擇的指標)

Would it be sensible to direct immediate efforts towards centre of
endemism that is those regions which contain significant numbers of
endemic species? (本地種的狀況)

As it is impractical to protect all biotic communities from pollution &
other impacts, what are the most effective methods for identifying the
most sensitive communities? (易受損性與相關威脅)

不同部份的內容需分開處理 (Shaw and Zube, 1980)
discussion about the difficulty of trying to define value, suggested that
the difficulty can be partly overcome by distinguishing between:
economic measures of value; social & psychological; ecological
measures.
