Finally a day when it was cool enough to get out on site with some machinery to get some of the paths trimmed. This is not the most glamorous of reserve management tasks but it has to be done. Managing a nature reserve is full of conflicting demands and dilemmas. No management is without impact and what is positive for one group of species will be negative for others. Trimming the paths often means cutting back nettles, as most will know these are the food plant of peacock and small tortoiseshell butterflies, so I try to avoid cutting the patches in full sun which they prefer and to do larger scale cutting only after they caterpillars have finished feeding.

The clearance of dense nettlebeds promotes patches of grassland and other herbage which is preferred by a wider range of species such as small skipper, which have just started to fly this year.
Over the years I have managed many different sites used for various purposes, ranging from nature reserves, long distance paths, picnic sites and Country Parks and these dilemmas occur at all of them. In truth all land management involves conflicting interests and all land is in multiple use. On a nature reserve wildlife will take precedence over most of the site, but access and safety will be paramount in some areas. I do believe that whatever the land use, it is wrong to deny the multiple interests, land management is about balancing interests not ignoring some entirely. Above all management should be about maintaining and enhancing the possibilities that are available for the future, good management is about increasing potential not applying a full stop.
Following Day 22’s horsefly picture I got another, this time of a male Hybomitra species in flight. This one is Hybomitra distinguenda and they fly very fast indeed, the picture was taken at 1/4000 sec and the wings are still in motion.
It is reputed that a species of this genus, albeit a rather large one from Southern Africa is the fastest flying insect having allegedly been clocked at 90 mph!
I have noted before how Blashford has many species that have come in from elsewhere, often due to the somewhat chequered industrial history. We have a number of coastal species including a very large population of annual beard grass, perhaps the largest in the county, the natural habitat for it is poached upper saltmarsh, such a scan be found at Farlington Marshes.
