We just have a Planter planting rubber trees, and a Harvester knocking them down again. Saplings go back to the planter with excess going to BioFuel generation, any wood is sent to an extractor to get rubber, and you get quite a bit of sticky resin from this too (we've amassed 30k or so, since the rubber wood is being extracted automatically we haven't even needed to use the sticky resin reserves yet).
