Farm: Todholes Farm, Caithness
Todholes Farm is a 170ha lowland livestock farm in Caithness, where Ian Campbell raises prize winning beef cattle and sheep.
Ian Campbell took over the 170ha holding around 1990. Previously his father had managed the farm, having moved to Caithness in 1951. Since then, Ian has built up a herd of prize winning livestock, and won many rosettes for his Beef Shorthorn cattle as well as Lleyn and Texel sheep at a county level and further afield.
Caithness holds nationally important populations of breeding waders such as lapwings, curlews, redshanks and snipe as well as twite, which have suffered from long-term declines in their breeding numbers across the UK. It is also a stronghold for the biodiversity action plan (BAP) priority species great yellow bumblebee which was previously widespread in the UK but is now one of our rarest native bumblebees. Populations of all these species have been maintained in Caithness thanks to high nature value farming systems. Todholes Farm is a typical example of these systems, which has been further enhanced through the tailoring of management for the benefit of key species.
The majority of the farm is grazed, with smaller areas of arable for livestock feed: spring barley for cattle feed, fodder rape for fattening lambs, and fodder turnips for wintering sheep.
Much of the farm is directly adjacent to the River Thurso, a Special Area of Conservation for Atlantic Salmon and a Site of Special Scientific Interest for a number of nationally rare or scarce plants.
Management advice was provided by the RSPB Scotland, specifically in relation to breeding waders and seed eating birds. Scottish Natural Heritage advised on management relating to designated sections of the site, and the Bumblebee Conservation Trust advised on the provision of pollen and nectar sources.
Of the options available for the non-designated parts of the farm, Ian opted for:
- Open Grazed Grassland for Wildlife (29ha)
- Management of Habitat mosaics (16ha)
- Management of Species Rich Grassland (4.5ha)
Open Grazed Grassland for Wildlife
Stock are excluded for six consecutive weeks between 15th March and 15th June, to restrict trampling of nests of waders such as lapwing and curlew. This could have had a high impact on the farm business, particularly in late spring, so the timing of the exclusions are calculated to allow two areas to be shut off while a third is opened up. This works well and has little detrimental impact on the economics of the business.
Management of Habitat Mosaics
This is an area of bog and heath with scattered rush and gorse bushes. Grazing is kept low between May to August to avoid trampling of wader nests and at the same time to avoid the vegetation becoming too rank.
Species Rich Grassland
Three areas of species rich grassland are managed on the farm. Wildflowers were relatively abundant right into early September, providing a much-needed late nectar source to bumblebees. In particular, the nationally rare great yellow bumblebee has been found on Todholes, and lapwings and curlews nest on the other areas of species rich grasslands.
There are some small areas of wetland within the habitat mosaics field, which were of concern to Ian in case they presented a problem with liver fluke. These areas were fenced off to address this. However, to prevent them from becoming rank, the wetlands still need to be grazed and cattle have access to them through the autumn/winter months. The cattle are dosed for fluke three times annually and Ian has not noticed any detrimental effect of fluke on his livestock as a result of grazing in these wetland areas.
It is still early days for the created species rich area and other taller more nutrient-loving species such as thistle currently dominate the field. Species that we hope will flourish here include vetches (e.g. tufted vetch and meadow vetchling), bird’s-foot trefoil and flag iris. Livestock are excluded between April and August but by the time the field is opened up again, the level of grazing is not sufficient to control the ‘weeds’. The grazing plan will be adjusted over time e.g. to increase grazing or allow for cutting so that a greater variety of plants can flourish. Some scarification and reseeding may also take place.
