有人提出,，表現(xiàn)差的保護(hù)區(qū)應(yīng)當(dāng)失去其保護(hù)地位,，所節(jié)省的資金應(yīng)用到效果好的其他地方,。這種觀點(diǎn)不易被保護(hù)工作者和地方游說(shuō)團(tuán)體所接受,。但根據(jù)對(duì)澳大利亞近7,000個(gè)保護(hù)區(qū)的表現(xiàn)所做的一項(xiàng)研究,，從長(zhǎng)期來(lái)看這種觀點(diǎn)可能是最好的政策,。
大約70個(gè)被取消資格的保護(hù)區(qū)（所評(píng)估土地的單位價(jià)值產(chǎn)生的保護(hù)價(jià)值最低的保護(hù)區(qū)）的出售,，可能獲得大約210億澳元（約177億美元）的資金。如果這些錢然后再重新投入到生物多樣性保護(hù)策略更可能獲得成功的保護(hù)區(qū),，將有可能以同樣支出獲得更大程度的保護(hù),。隨著全世界保護(hù)區(qū)的新投資額持續(xù)下降,，本文作者們提出，面對(duì)破壞植被行為的泛濫猖獗,，保留那些最有價(jià)值,、最有生產(chǎn)力的區(qū)域比以往任何時(shí)候都顯得更為重要。(生物谷Bioon.net)

Replacing underperforming protected areas achieves better conservation outcomes

Protected areas vary enormously in their contribution to conserving biodiversity, and the inefficiency of protected area systems is widely acknowledged1, 2, 3. However, conservation plans focus overwhelmingly on adding new sites to current protected area estates4. Here we show that the conservation performance of a protected area system can be radically improved, without extra expenditure, by replacing a small number of protected areas with new ones that achieve more for conservation. Replacing the least cost-effective 1% of Australia’s 6,990 strictly protected areas could increase the number of vegetation types that have 15% or more of their original extent protected from 18 to 54, of a maximum possible of 58. Moreover, it increases markedly the area that can be protected, with no increase in overall spending. This new paradigm for protected area system expansion could yield huge improvements to global conservation at a time when competition for land is increasingly intense.
