The Wild Chervil, and What We're Doing About It

Somewhere in the first week the herd spent on grass, working through the first pass across the old field on the north-west side, a plant turned up that we could finally put a name to: wild chervil. Lacy leaves, a member of the carrot family, and — less charmingly — an invasive that spreads fast once it gets a foothold. It sits in patches, heaviest along the strip edges, and at a rough eye it's about a tenth of the standing growth out there. The cattle mostly step around it. It isn't something they choose to eat.

That last part is the catch, and we'll come back to it. First, the plan.

The plan, said out loud before we know if it works

The idea is to let the herd deal with it. Pack the cattle in tight enough on the chervil patches that they graze and trample less selectively — pass after pass — and try to catch the plant before it flowers and sets seed. Interrupt a season's seed before it lands in the soil and, in theory, the patch has a harder time coming back the next year. That's the theory. It's also roughly how the same trick has worked on other weeds in pastures like ours.

How honest do we want to be about that? Very. The grazing science behind the idea holds up as a principle — crowd cattle and they'll eat things they'd normally walk past, and hitting a weed before seed-set is well-established as a way to slow it down. But that work was done mostly on other plants, like Canada thistle, and on Quebec's own invasives with cattle the record is thin. Whether it knocks back wild chervil, on this ground, with these cattle, nobody has measured. So call it a hope with a decent mechanism behind it — not a plan we already know will land.

And the catch from up top: the cattle mostly avoid the chervil. Crowding them is supposed to make them less picky, but there's a point past which even a hungry, tightly-packed animal will simply refuse a plant. We don't yet know which side of that line wild chervil sits on for our herd. It's entirely possible the answer is that grazing alone isn't the right tool here — and if that's the answer, it goes in the record too.

Why we're telling you before it's a success

It would be easy to keep quiet about a weed until we'd beaten it, then write the tidy victory piece. We'd rather show the work. We marked where the patches are on this first pass, and we'll compare them on the next one — did they shrink, hold, or spread? If the chervil spreads instead of shrinking, that's not a paragraph we get to delete.

Whether that actually knocks it back I don't know yet — it's a hypothesis, not a result. […] If it spreads instead of shrinking, that goes in the record too.

A setback we're honest about early is the fastest proof that the honesty pledge means something. Anyone can publish the wins. We keep a dated, signed record of the whole thing — the misses included — because a record you can hold someone to is the only kind worth keeping.

The raw entry, written the evening we found it, lives in the Almanac's field notes. This is the story; the receipt is there. We'll add the next chapter — better or worse — after the following pass.
