I mulch over them but not right away. Spring-falling maple seedlings such as those from silver maples don't have a real long viability (Norway maples have longer-lived seed, darn them -- but their seed falls in late summer/fall so it's not what you're dealing with now. Sugar maple seeds last longer, too, but they need a month or more of cold, moist conditions before they sprout, and they, too, fall late in the year not now.) Most lose ability to germinate in just a two to three weeks, and that loss of viability is accelerated if the seeds are allowed to dry out.
So let them lie, don't cover them which could conserve moisture, and hope there is not soaking rain until you do mulch over them.
Did you know -- cottonwood, elm and willow seeds last even LESS time after falling? If they don't find favorable conditions for sprouting within a few DAYS, they're toast.
I know they're a pain, tree seeds. Yet having others to talk about obnoxious seeds is great, isn't it?

I'm going to spray them with Roundup...and then apply a mulch of leafmold.
If this happens again in the future...two years from now...I shall be sure the lawn sprinklers are not turned on for the first three weeks!
