Linje 28: En mindre skov kaldes for en '''lund'''. Skove med træer, som har dybe [[rødder]], har en væsentlig indflydelse på [[klima]]et og den dybere [[jord]]s vandindhold. Træernes rødder kan transportere op til 10% af den årlige [[nedbør]] i vådsæsonen fra overfladejorden og til dybere jordlag -– ned til 13 meter. I tørketider "henter" træerne så vandet igen og kan på denne måde lave op til 40% mere [[fotosyntese]] i [[tørke]]perioder. <ref>[http://www.sciencedaily.com/releases/2006/01/060112035906.htm University of California -– Berkeley (2006, January 13). Deep-rooted Plants Have Much Greater Impact On Climate Than Experts Thought. ScienceDaily] Citat: "...The tap roots transfer rainwater from the surface to reservoirs deep underground and redistribute water...increases photosynthesis and the evaporation of water...by 40 percent in the dry season...During the wet season, these plants can store as much as 10 percent of the annual precipitation as deep as 13 meters (43 feet) underground, to be tapped during the dry months...tree roots acting like pipes to allow water to shift around much faster than it could otherwise percolate through the [[jord\|soil]]..."</ref> <ref>[http://news.bbc.co.uk/2/hi/science/nature/7003788.stm 24 September 2007, BBC News: Amazonian forest 'more resilient'] Citat: "...Although increased photosynthesis in drought conditions might appear counter-intuitive, the group said it could be explained if the trees were still able to access water reserves with deep root systems...The key thing here is that the tree roots access water deeper than is often represented in models...more frequent drought conditions would eventually diminish the deep-water stores, and make the trees suffer..."</ref> <ref>[http://www.sciencedaily.com/releases/2007/09/070923193644.htm University of Arizona (2007, September 26).
