* More than 11,000 sightings were reported to the People's Trust for Endangered Species during last year's national Stag Beetle Challenge. Since most were from people's gardens in and around towns and very few from the countryside, this summer's survey aims to "fill in the gaps". Keep your eyes peeled, especially on warm, summer evenings between now and September, and send your reports to PTES at: 15 Cloisters House, 8 Battersea Park Road, London SW8 4BG, tel: 0171 498 4533.
* One hundred years ago, 115 observers provided the Royal Meteorological Society with records on the flowering of 13 plants and the appearance of various birds and insects. In a bid to revive this scheme, The Institute of Terrestrial Ecology is inviting schools, conservation clubs and youth groups to fill in recording sheets while out on nature walks.
