End of July report

Everything still going swimmingly and a targetted completion of end September currently requires a rate of 3 spp./day, which is about where the rate has been since February.

It's hard to believe that the same rate can be maintained but we are still in high season and perhaps it's harder to believe it won't. Moths have plenty of life left in them. Migrant birds are starting to filter through. A major sweep for plants is still turning up new material and there are all those spiders coming into maturity. Flies have been a little neglected in the last week or two and there must be some joy to be had there. Last but not least fungi are definitely ramping up as we get to the end of the summer.

Year progression, compared to previous "year efforts" at my local reserve.

Year progression by class, showing the recent emphasis on plants, the start of the fungus season and the arrival/passage of the first migrant birds
