Fellowes (2002) 將本地分佈局限性定義為一項量度野生動物對特定地點的依賴。地點以一平方公里為單位。分佈局限性越高的物種，就越容易因為生境消失或生境破壞而滅絕。本地分佈局限性可簡單地分成七個級別：

A = 只在 1 個地點出現；

B = 在 2 個地點出現；

C = 在3個或4個地點出現；

D = 在5至8個地點出現；

E = 在9至16個地點出現；

F = 在17至32個地點出現。

Fellowes (2002) defined local restrictedness as a measure of dependence of wild animals on particular locality, versus other localities of comparable size in Hong Kong. A locality is taken to measure 1km2. A highly restricted species is most vulnerable to local extinction through habitat loss or damage, and its very restrictedness is a reflection of high habitat specificity. Local restrictedness is simplified as follows:

A = known to occur in this locality alone;

B = known to occur in two localities;

C = known to occur in three to four localities;

D = known to occur in five to eight localities;

E = known to occur in nine to 16 localities;

F = known to occur in 17-32 localities.
