Hubbard Brook: The Chemistry of a Forest

Alternative title

Temperate Forest Chemistry

Synopsis

Features the long-term ecosystem study of a northern hardwood forest - the Hubbard Brook experimental forest in north-eastern USA. Research has shown the importance of monitoring the entire ecosystem when different harvesting regimes are introduced and as well as the importance of maintaining plant cover to mitigate the loss in soil fertility when trees are harvested. Scientists have been able to monitor all the important inputs that stimulate forest growth, and also virtually all the chemicals, nutrients and water draining each watershed. The long-term records from this forest enabled scientists to prove that acid rain was more than a local phenomenon.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
