Pest Control Policy and Plan
Introduction We have a duty of care under the Agricultural Act and the Injurious Weeds Act to manage and control pest species listed within the Act. As far as Coombe is concerned these are mainly rabbits, pigeons, crows and one species of plant, ragwort. Furthermore we are obliged to manage pests as part of our site management agreement of the SSSI this is covered by the Wildlife and Countryside Act, species covered by this Act are; Rabbit, Grey Squirrel, Mink, Canada goose, Cormorant, and three species of plant; Indian balsam, Ragwort and Rhododendron. We have tried a variety of methods over the years to reduce these species and maintain a balance for nature conservation and our neighbouring farmers. Situation Statement The Successes There is an annual programme of Ragwort control that really appears to be having an effect. We have tried a variety of control methods over the last five years, these have included the use of a product called Barrier H a natural plant extract, spot praying and a pulling programme; the most effective appears to be the pulling program we are assisted in this work by various conservation groups and individuals. Rhododendron control continues, and has progressed very well in the last five years due to the concerted efforts of the estate team and various volunteer groups, this project would not have been possible without the added assistance of this voluntary work force. The spraying of secondary growth has not been carried out as effectively as I would have liked and this needs to be addressed during the next five years. Indian Balsam is being controlled with the use of our volunteers, much the same as the rhododendron, this is an ongoing process, the emphasis is to concentrate our efforts on the SSSI and ditches and to work out form their, this approach has worked well over the last couple of years and will be extended into the next five years of plan. Canada Goose numbers have been successfully reduced to manageable numbers we will continue to egg prick annually and we will cull again should numbers increase again. Getting there but not quite Cormorant management has been difficult. We now manage the fish stocks to prevent predation by providing fish refuges made from gabions but this only deals with one side of the issue. The damage to the heronry trees is still considerable, we have had limited success with the use of crop scarers, as this document is going to press we are starting to a new program of scaring using an inflatable scarer this appears to be working, time will tell. Working hard but only scratching the surface Squirrel damage to new and established trees on the site has to be seen to be believed. Approximately 70% of the trees planted since the 1980 s have seen some damage, 100% of the deciduous trees planted in the formal gardens have some sort of damage, many have died and been removed. A more targeted approach to the control of this species is required. This will be adopted over the next five years. Failing dismally Rabbit problems are considerable; we have spent nearly 7,000 on control methods from pest control companies in the last three years. Due to the very mild winters rabbits are now breeding year round, with many living above ground, making the usual method of ferreting less successful, although it still controls a fair number. Estate staff have been reporting substantial damage to the base of trees, as they manage the new plantations; what the squirrels don t get the rabbits will!! They are also causing damage to the grassland where their warrens are getting bigger. Action plan for the next five years An action plan for each species has now been drawn up for the next five years this will provide us with a proposed action, methods of control, and a best practice guideline. Monitoring of the process will be done as an annual review of the action plan this will form part of the site s annual work programme. J P Taylor July 2011 Pest Control Policy and Pan 1
Pest Control Plan 2012-2017 Introduction This plan deals with those species of plants, mammals, and birds that are either registered pest species or those species that are nonindigenous and are having a detrimental effect on priority species and habitats at Coombe. It will highlight the species, the reason for control measures being taken, what control measures are in place, monitor existing practice, and make recommendations for the future.
