A possible long term solution to reduce fires in shrub lands could be to plant native trees that have large canopies to increase the forest canopy coverage. this could naturally reduce the amount of shrubs and underbrush (fuel load) in the area.

I have no idea if this would net a increase or decrease the transpiration however.

You need to study the long term effects of the prescribed burns are likely to be in re-guards to the reduction of transpiration, and how the lack of rainfall to those areas down wind.

Also, you need some way to measure and then deal with the extra watter artificially keep in the areas of the prescribed burns. For all that extra run-off to end back in the ocean would truly be a waste of resources.

Prescribing burns you are artifcialy reducing the effects of transpiration to increase rain watter catchment. This effects people, plants, and animals from lack of rain fall amounts down wind. In a scene creating a lake filled oasis in one place where you have prescribed burns to reduce transpiration and in turn causing a drought like rainfall down wind.

less foliage and brush reduces the re-evaporation of the rainfall and increases the amount of rainfall stays in the ground or is run-off into rivers and streams, that i get. The ecosystem balances rainfall by naturally burning areas where the soil dry through naturally high levels of transpiration.
