Fertility of Prunus spinosa

I enjoy making and consuming sloe gin using the fruits of the blackthorn (Prunus spinosa).

I have noticed that fruit only appear on bushes in particular localities.  In the spring there are large areas that are white with blossom but, at this time of year, I find sloes only on certain bushes.  Large expanses of bushes are totally devoid of even a single sloe. The same areas are fruitful from year to year, although the crop can be heavier or lighter.

Are there male plants which cannot fruit (Wikipedia seems to indicate that the flowers are hermaphrodite)?  What other reason can there be for such a marked difference in the fertility of this plant?

     Thank you
