Over the past year or so the remit of this blog has widened first to include the whole garden, and then to include the allotment. This has mainly been because the meadow is not really large enough to warrant a journal of it's own now that it is fairly well established. I suppose I should really do a thorough survey of the plant species present and their relative abundance. But then again, what would the point be? This is a small patch of introduced grassland with 'native' species in the midst of a sea of sterile lawns. Surveying it would document how well the seeds and plants introduced had established but this is not exactly ground breaking research. In fact it would be much more useful to survey the invertebrates. This vital nugget of information comes from a book I recently read by Ken Thompson called "No Nettles Required" which gleefully overturns many of the cherished tenets of wildlife gardening. It does so with real authority as well since it is based on the only comprehensive survey of garden wildlife so far carried out, Sheffield University's BUGS project. It makes plain that the level of biodiversity on which the garden operates is that of invertebrates; while birds and to a much lesser extent mammals and reptiles use gardens, few actually spend their whole lives there. Moreover, among the huge range of species they uncovered in the urban gardens of Sheffield were a number which were quite rare and some which were completely new to science! The most important point they discovered was that the presence of native species made no difference to levels of biodiversity in gardens. So to study the impact our meadow i would need to place a range of moth, beetle and other insect traps and study the results. The problem is that unlike the BUGS project and Jennifer Owen (author of the seminal Ecology of a Garden) I don't have access to a large number of experts in invertebrate identification and while I can identify many insects to the family and in some cases the genus level, there is a limit to my skills. And my time.
This does however justify including the whole garden within the remit of the 'meadow project' since it is the biodiversity of the garden I am interested in. It makes no sense to apply one set of values to one part (the meadow) and an entirely other set of values to the another part (the ornamental and vegetable gardens) when all areas are potentially equally valuable to wildlife, as long as certain rules are adhered to. Specifically no pesticides. I have only used 'organic wildlife friendly' slug pellets but I think that these are out too now. However on the allotment the principal aim is feeding the family so I won't be so 'sentimental', and unless it is relevant to the garden I won't dwell on it further.
If I can't identify every invertebrate in the garden in a rigourous and scientific manner I can at least document at least some of them in an entirely partial and unscientific way. To this end I will:
- try to document photographically all species observed in the garden when I get time...
- continue to develop the pondcam, once I have fixed it...
- create new MeadowCam to replace the fixed point pictures. This will be a time lapse of the changes occuring across the meadow using a Canon compact and GB TimeLapse software. When I have figured out how to do it. Which I should have got done by spring...
So here's to the future.
