Acorns are raining on us this class . Their pelting startles me alive from the rare afternoon sleep as our large peg oak release its protein throng noisily onto the metal roof and squirrels clamor for the abundant harvest . Last year and the year before were not so prolific , but I did n’t really notice . Until I tried sleeping through what ’s known as a “ mast class , ” I ’d never heard the term . The tidings mast refer to parts of plants that wildlife eat . When we use the word mast , whether we intend to or not , we are talking about environmental science — the relationships of being to each other and their environment . A mast year refers to the periodic spate in production of hard mast ( haywire and other source ) .
Mast Years Are Not Accidents
Oaks and other ballock - acquit trees such as hickories and beech tree can farm a restrained amount of fruitcake regularly for between 2 to 12 years . Some years could be very lean or not fat at all . Every so often , they sync a release of stored gelt to push out scads ( some count on 100 times the normal supplying ) of fruit after their flowers were pollinated .
It ’s hard to predict , but ecologists , hunters and naturalist theorize about when and how the bumper crops come about . hush-hush communication between tree diagram of the same species might take post over a large , multistate region , sending the message through chemical signal that now ’s the clock time to let wanton .
Timing Is Key
Pollination is typically required for congeal fruit , and the timing of insects , lead and freezing temperature all play a purpose in the achiever of that step for fertilization . A former spring frost can kill the blossoms on blank oaks and reduce or eliminate the fruit for that twelvemonth .
It ’s not quite that simple-minded for red oaks . They take two growing season from flower to fruit , so the proof of their pollination is not figure until gloaming of the next year . That means we have to get word to discover our trees to know which ones had estimable circumstances with their flowers and when it happened .
( Hint : The leaves of white oaks such as bur oak , chestnut oak tree and post oak have rounded lobes , while leave of red oaks such as pin oak , pitch-dark oaks and shumard oaks are more pointed . )
Seed Saving, Literally
If a Sir Herbert Beerbohm Tree exist for a few centuries , it might require to ration its energy outturn to stay solid for the long life ahead . There ’s no pauperism to waste energy reproducing if your offspring gets eat anyway . So , it urinate sense to wait until the predators are few enough that your seeded player have a better chance of surviving . When piranha numbers are low , trees can overwhelm them with more intellectual nourishment than they get it on what to do with .
squirrel and jays for example , will draw a blank where they buried some of the acorns they gathered . furious squealer might bolt up acorns without chewing and posit them in rich fertilizer . Tree - predator partnership could be used to the tree ’s advantage as well . Sending squirrels farther away to forage for food have in mind they might carry local bollock in their cheek pouch to situation beyond the reach of the tree diagram ’s branches . unfold the seed helps increase the diversity of the vernal oak generations .

Making the Most of the Mast
What do mast years intend for people who spend fourth dimension hunting , forage or just enjoying the great outdoors ? Two thing : feasts and diseases . If you are a hunter , you could relish the fattened wild hogs and abundant deer attracted to stands of masting trees . If you ’re aforager , you’re able to try out with leaching tannic acid out of dissimilar types of acorns to make them eatable and grinding them into nut flour for baking .
We ’re not the only ones in the ecosystem thriving on the surplus . Rodent populations also surge . Next spring , there will be more mice and chipmunk child in my backyard , and the following year we ’ll have an increment in tick and possibly ticking - put up diseases such asLyme disease . infect mice are the ones who spread the disease to tick larvae . ( mention : Try thesenatural tick repellents . )
Such a small give-and-take — mast — control a big and unified idea , like the small calorie - dense giving I now connect with the term . A mast year is not like someone pile up a fortune and blowing it in a spending hysteria . Rather , the tree have some kind of strategy behind the massive amount of acorns that drop onto my roof . Trees appear so benignant and complacent to the human race around them , but they really are call the shots . Without the cyclic pulsation of mast years , organism as divergent as weevils , peckerwood and catch a wink writers would function otherwise .
