An old brass valve and a chunk of magnesium casing from an old saw can produce a bit less than 1 volt with salt water. Six jars can power a 4.5 volt transitor radio very well 50 mA . Nowadays the current requirements for electronics is a tiny fraction of what it was. The metalurgy of today means the middens of populated area is strewn with scap metal.
What other batteries can be made from junk that work well? How about an organic battery or an osmotic battery from plants?

If you place metal rods on either side of a stream, a voltage is developed. Rods in trees could gather electricity generated as water is drawn up the trunk, and if you short circuit the rods, the earths magnetic field will be changed.
Would the voltage be equal to earths field * distance between rods * rate of water flow * the sin of the angle of the treetrunk to the earth field. ?

I know that I used to stick electrodes in with a house plant to power a small clock - I wonder: could you leave some heavy duty electrodes with a relatively fast growing tree, such that they might be combined more effectively with the process as the tree grew? or this might be bad for the tree?

Have you considered if the energy comes from the electrodes being consumed, rather than the plant being electric?
I figured that, but what I meant was that if electrodes were "grown in" I wonder if the chemical process would be more efficient, as the tree which supplies the proper environment for the electrodes will grow around them, rather than just plopping the electrodes in.

The collectors for trees should only work in the cambrian layers as the corewood doesnt live but does maintain a moisture level. If the magnetic model works it requires a fluid movement, The collection could involve a fluid tube inserted interstitially at the ends of the tubes, the metalic collector could be the terminals.
Trees are amazing chemical systems with interesting branch/leaf patterns. Its doubtful if they operate at so coarse a mode to require longditudinal electric currents.
