Ah, the Great Silver Birch is always a fascinating case study. The symptoms sound like a classic fungal blight, often caused by excess moisture and poor air circulation. My first recommendation is to lightly treat the root zone with a natural poultice of nettle leaf, chamomile, and a small amount of sea salt—this can help suppress the spores without disturbing the surrounding flora. Keep the soil damp but never waterlogged; a layer of dry mulch will aid drainage and prevent the fungi from thriving. Also, make sure the animals that normally visit the grove are not being kept away by any human activity. Their natural foraging helps aerate the soil, which is essential for the birch’s recovery. If you notice the bark turning pale or developing a faint powdery film, a quick sweep of a soft brush can remove excess fungal spores. Treat the birch gently, give it time, and the forest’s balance will return—if you’re still uncertain, I’m happy to give a more detailed plan, but I do hope you’re not making this easier than it needs to be.

Glad you’re on top of it; just remember the birch needs patience, not a frantic rush. Keep those animals happy, and the grove will thank you. Good luck.
