Spring again at Kah Tai

The monthly workparty at Kah Tai focused on invasives. The particular invasives being wrestled were tiny hollies and spurge laurels in the woodland, found in abundance at the bases of trees, byproducts of bird digestion of the fruits of hollies and spurge laurel. The best way to pull a tough two inch plant with a five inch root is sitting on a garden stool with a pair of needlenose pliers.

While concentrating on the seedlings, it suddenly seemed I wasn't the only presence in the woodland. Sitting on my stool, I looked west and a few yards away was a head atop the flexing neck of a Canada Goose. Our eyes were at about the same height but the big bird didn't see me. He or she moved slowly toward the lagoon edge and another goose head came in to view a few feet behind. And there between the two adults, a flock of little goslings scurried along. Their parents were marching them from their nesting site to the water with cautious deliberation.

The lead goose reached the trail that runs along the southern edge of the lagoon and the procession paused while both directions on the trail were studied for danger, for people on foot or bicycle, for dogs. The lead goose determined that the trail was safe, and the family hurried across the trail and into the lagoon.

Shortly after they launched, a human family passed by on the trail, two small girls in tow.

'Mommy, look!' The goose family at the edge of the lagoon were admired by the human family.

A minute or two later, a group of four human teenagers passed in the other direction.

'Look! Goslings!'

The level of enthusiasm from the little kids was expected, but who knew teenagers would think goslings were cool?

And then, back to the needlenose and pulling minute invasive seedlings. Among the invasives, much good news. Seedlings of serviceberry, snowberry, thimbleberry, osoberry, taking a stand, all planted by birds as indiscriminately as the invasives were. But as the native berry sources mature, the birds will be less likely to feed on holly and spurge and more likely to continue the cycle with native species. More native understory, fewer invasives.

In the open areas of the southern park, the tall mahonia has burst into dominance, suddenly competing successfully with invasive blackberry, with bright yellow blossom heads peering through blackberry canes. The nootka rose has been pushing back against the blackberry for several years and it now has another native comrade in arms. We might, actually, be winning this particular battle for Kah Tai.
