This summer, fewer Western snowy plovers launched their offspring into adulthood. There were only 71 fledglings coastwide this breeding season, compared with 124 last year. But biologists kept their wits. They aren’t happy about the results, yet they aren’t panicking either.

The plover watchdogs were quick to thank people for following beach rules and staying off the dry sand in the protected areas. Whether or not people intentionally heeded the rules, the New Carissa shipwreck salvage project made getting to the North Spit a challenge.

Perhaps ironically, the clang and bang from the New Carissa salvors didn’t seem to affect the North Spit’s plovers. They did just fine: Their 40 chicks were more than half the Oregon coast’s total.

 The lesson learned here could be that some non-polluting industrial operations can happen close to sensitive wildlife areas. The New Carissa project seems to have kept a lot of people off the beach, and that’s typically the case in industrial areas. People stay out. So maybe there will be opportunities for biologists and industry to be good neighbors in future efforts to protect habitat and revitalize species.

This summer’s success on the spit but fledgling failures elsewhere shouldn’t be interpreted as a reason for a rash reaction on the part of regulatory agencies. And it doesn’t appear they view it that way, either.

If you look at the production graph since biologists started pampering plovers, it’s a line solidly on the rise. As with anything in nature, the data proving a trend takes a long time to gather, and a one-year setback in reproduction is not a cause for panic. Unlike gasoline prices or the housing market, a bird population is not a bubble prone to bursting.

This is not a bird whose doom has come. Its population is recovering, and this year’s stumble was likely nothing more than part of a natural cycle. It’s heartening that the scientists didn’t overreact.
