You're not wrong Kansas Cat! This conundrum has got me in a quandary, and I'm curious as to what you're experiencing where you are. What we're seeing here is that anything less than annual burning leads to serious woody plant invasion, but we also are told that annual burning leaves no cover for nesting grassland birds (including GPC, though anecdotally, I do chickens nesting in annually burned prairie. No idea what the success rate is...). However, there is also good research showing that the presence of trees in even loose proximity to grassland bird nesting locations is detrimental to them...so we need to keep the woodies out too. Not burning hurts the birds because it lets woody plants in, but burning to keep the woodies out kills the birds. In this situation most managers turn to the chemical companies. That's got a different suite of problems, and probably isn't a good long term solution. I've tossed around the idea of adding browsers to the system, they'd harm the woody plants and lessen the role that fire would need to play, but that's an unpopular idea with its own suite of problems...maybe staggering and rotating the seasonality of fire in your pastures, so that some are burned after nesting season is over and early-burned pastures have regrown?
Any thoughts or advice? What kind of burn rotation do you do? Have you seen plum, dogwood, pricklyash, honeylocust, etc. coming in? If so, how do you deal with it?
