Under the Köppen climate classification the farm sits within the classification Cfb:

Temperate oceanic climate; coldest month averaging above 0 °C (32 °F) (or −3 °C (27 °F)), all months with average temperatures below 22 °C (71.6 °F), and at least four months averaging above 10 °C (50 °F). No significant precipitation difference between seasons.

The closest weather station to the farm is at Kingarrow, 6 miles to the south-west. As you will see from the data below, the farm receives in the region of 2,000 mm (78 inches) of rainfall annually.

Prevailing winds are from the south-west for most of the year, with cold snaps blowing from the north & north-east. Due to high average wind speeds, shelter is of utmost importance for livestock management particularly during the winter & shoulder seasons.



Think of Donegal and the usual image that springs to mind is one of stark, barren hillsides and muted heather tones. This may be accurate of today’s vista, but the misconception is to believe that this is the way it has always been. The names of surrounding townlands reveal a different story…

  • GLENVEAGH; Gleann Bheatha (Bheithe) translates as “Glen of the Birch Trees”.
  • DERRYVEAGHCnoic Dhoire Bheatha translates as the “Hills of Oak & Birch”.

A combination of factors has led to the denuded landscape we know today; including the introduction of Red Deer to the area in the mid-1800’s – which have since gone virtually unmanaged – & the expansion of grazing on these hills in more recent times.


Land Units

An Caora Dubh Farm is a fairly typical of an upland farm in the west of Ireland. The sites lie between 80 m & 300 m above sea level & discrete land units fall into one of three broad categories as follows:

  1. Rough Grazing / hill – typically characterised by rough grasses, heather & an ineffective water cycle (leading to acidic / anaerobic soil conditions). Often, but not always, the higher elevation sections of the landscape.
  2. Pasture – long established grassland or grass/rush areas, either improved or unimproved through prior drainage or lime.
  3. Native Woodland – areas that have succeeded to later stages of succession due to lower grazing pressure; either as a result of livestock management or inaccessible terrain.

Land Use

Traditionally used as livestock pasture, with lower lying grass lands grazed in the shoulder seasons & rougher areas grazed as part of a summer rotation. Some areas of in-bye land exhibit signs of previous working as vegetable plots with ridges still visible. Evidence of up to 5 families having lived on various parts of the property in times gone by, though not necessarily at the same time.
