The Albany Thicket Biome is highly resistant to a wide variety of disturbances but, once disturbed, lacks the regenerative qualities that allow it to return to its original stable state. This study investigated the degradation status and the remaining extent of intact thicket. Classification of each thicket type was determined using Maximum Likelihood Classification and patch analysis using Fragstats. Of the four major divisions of the Albany Thicket Biome, classification of the Mesic, Valley and Dune Thickets were successful. The classification indicated that almost half of these thicket types has been lost, transformed or degraded by agricultural or urban development. For Dune, Mesic and Valley Thicket, thicket fragment sizes ranged between 6 and 876 km². Dune Thicket contained the smallest fragments (2 km²) of intact thicket, while Valley Thicket contained the largest fragments (251 km²) of intact thicket of the major divisions of the Albany Thicket Biome. The misclassification of Arid Thicket precluded an accurate determination of the level of degradation and a different approach to assess the degradation status will have to be devised for these open thicket areas that contribute 39% of the original extent of the biome.

奥尔巴尼丛林生物群系对各种干扰具有很强的抵抗力，但一旦受到干扰，就缺乏使其恢复到原始稳定状态的再生特性。本研究调查了完整灌木丛的退化状态和剩余范围。使用最大似然分类和使用 Fragstats 的补丁分析确定每个灌木丛类型的分类。在奥尔巴尼丛林生物群落的四个主要部门中，Mesic、山谷和沙丘丛林的分类是成功的。分类表明，这些灌木丛类型中几乎有一半已因农业或城市发展而消失、改造或退化。对于沙丘、Mesic 和山谷灌木丛，灌木丛碎片大小介于 6 和 876 km ^{2 之间}。沙丘丛林包含最小的碎片（2 公里² ) 的完整灌木丛，而山谷灌木丛包含奥尔巴尼灌木丛生物群落主要分区的完整灌木丛的最大碎片 (251 km ² )。干旱丛林的错误分类妨碍了对退化水平的准确确定，并且必须为这些占原始生物群落范围 39% 的开放丛林区域设计一种不同的方法来评估退化状态。
