Taking the long view: an introduction to natural England's long term monitoring network 2009-2016.
Natural England's conservation strategy for the 21st century, Conservation 21, sets out an ambitious, long term vision of how to work together to protect England's nature and landscapes. Natural England's Long Term Monitoring Network project (LTMN) began in 2009 with the aim of developing a cost effective network of sites to provide evidence on the effects of changing climate, air pollution and land management on the natural environment. It is a set of intensively monitored sites across England, selected to cover the whole country and to include some of our most valuable habitats. LTMN extends and complements the UK Environmental Change Network (ECN) which was established in 1992.
