Long-time allergy sufferer here, primarily dusts and moulds, but with an adult-onset specialty in tree pollens, specifically birch, and members of the
rose family. I get a mouth-feel itch from uncooked
apple, pear, and most pit fruit, including peaches, apricots, plums, and cherries.
One technique for managing pollen load is to ensure that you have female trees and shrubs of dioecious species in the hedgerows and beds around your house. Not only will they obviously not produce pollen, but they are also charged (positive, I think, to the pollen's negative charge, if I remember correctly) to attract pollen, effectively turning them into giant static pollen traps, if not filters, per se.
I came upon the idea for this as-yet-unproven solution when reading up on why urban allergy sufferers had it so much worse in recent years.
The answer had to do with a preference on the part of urban planners for male trees, as female trees produced far more seasonal debris. This of
course results in an increasingly overwhelming pollen load.
I don't think we have the technology, but I think we could develop charged pollen filters like the fabric barriers we string between sensitive crops. Imagine fabric barriers strung along property lines or around houses and living spaces, light, almost transparent sheets capable of holding a positive charge, perhaps powered by fencepost-top
solar panels, that attract airborne pollen while their slight daytime charge is being fed. So during the day, or possibly only during especially problematic times, the charged sheets draw the pollen from the air, to then drop most of it at dusk, where it can be used by soil critters for food.
But if mowing more is the only effective management solution, don't despair. The deer really aren't going anywhere. Toss some butternut or pumpkin into the woods for them and watch it
volunteer next year if you have any doubts. I would pay attention to when your former deer habitat blooms, as the other factor is obviously its value to pollinators, but if you let everything flower, or even just most of the early stuff, you'll retain most of those benefits anyways.
Hope you can find some happy outcome here. I don't understand it, personally, beyond the aesthetic. My outer hedgerow design features barrier elements against deer so the bloody hoof rats don't eat every damn thing that grows. They're beautiful creatures, and I love meeting them on morning walks, or seeing them from the canoe, but close to my gardens, they're just begging to be turned into cold-smoked venison.
Good on you for thinking of the bloody hoof rats, though. If they can't live a life absent humans, at least some of their human interactions can be positive.
