Wood in playgrounds can become a biotope for various fungi if one allows it: The spectrum ranges from blue stain fungi without the ability to decompose wood to slowly decomposing soft rot fungi to the wood-destroying basidiomycetes with low to high capability of wood decomposition. Keeping water away or reducing wood moisture is the fundamental intention of wood protection by design. Some rot fungi almost only degrade the sapwood, others prefer the heartwood and still others like to start in the sapwoodand then move on to the heartwood to expand. By knowing the rot fungi involved experts can better estimate the remaining service life and provide instructions for further checks.
