Leaves don't weigh lot individually, however how much weight do they collectively add to a tree as soon as it is in complete leaf?

Hi Chris,I think they add quite a lotespecially under pouring rain!...strong winds room probablyapplying significant forces too.Talking around plant EXPERTS!funkod  <

a mature healthy tree deserve to have anything in between 100 and also 200,000 leaves, with the load of each sheet being about 5g (but with vast internal variability). So if we take 150,000 together a mean, then that method 750,000 g or 0.75 tons (for a deciduous tree. There is far less weight fluctuation because that needle mass in a conifer). However, over there is the variable of stored carbohydrate going towards the growth of the leaves which already are contained in the weight of the tree, as well as the reality that numerous trees have already developed the following years leaves and also flowers in ~ the bud, so in actuality, the weight increase to the tree may not be all the great. The genuine weight increase in the tree is firstly the water used within these new leaves, and secondly the annual growth in the stem and branches. In a tires spruce forest in Britain, this deserve to be approximately 24 cubic metres every hectare (about 20 tonnes), conversely, an oak stand have the right to be together low together 3 or 4 (just under 4 tons). So per spruce tree, this would certainly be a network weight assimilation of about 30KG every year ~ above average.There are various other masses to incorporate - rainfall (and this causes a high level of load fluctuation in ~ the entirety tree - the tribe measurably grow and shrink depending upon the water availability), pollution depositions, insect mass and so on etc...
