How often should cutblock boundaries be reinspected?

There's no fixed interval that applies across every file. It depends on what triggered the last inspection and what tenure class the block falls under, and anyone who gives you one flat number hasn't had to defend a monitoring schedule to an auditor or a certifying body's own reviewer.

That said, most compliance programs end up running on a base cycle, then pulling blocks forward off that cycle when something warrants it.

The base cycle most programs default to

Base cycles get set by whoever holds the regulatory or certification mandate, and they're set as much by budget as by risk. Field crews, flight hours, and inspector time are finite, so the "how often" question usually gets answered by dividing the active cutblock count by however many site visits the program can fund in a year. A tenure with a clean history and stable terrain might sit on a longer rotation. A tenure with a prior finding, or operating under a new licensee, often doesn't get that luxury even if the calendar says it's not due yet.

What should move a block up the list

A handful of things reliably pull a cutblock ahead of its scheduled date:

• A harvest plan amendment filed mid-operation, particularly one that shifts a riparian buffer line
• A complaint from an adjacent tenure holder or a neighboring landowner
• A prior overcut finding on the same operator, even on a different block
• Steep or broken terrain, where boundary drift during falling is more likely
• A gap between what the permit shows and what the cut looks like once harvest is underway

That last one is the trigger most programs catch latest, because it depends on someone comparing the imagery to the permit before the file ages into its next scheduled round. If nobody's looking in between visits, a buffer incursion can sit unflagged for the better part of a year.

Where a remote first pass changes the schedule

Most reinspection cycles stay reactive because the only way to know a block needs attention sooner is to send a crew and look. That's expensive, and it means the schedule mostly responds to complaints rather than to what's on the ground. A program that layers in a remote comparison of the cut against the permitted boundary and buffer, run on a fixed cycle instead of waiting for a call, gets a different answer to the "how often" question entirely: keep the field schedule you can staff, but flag the files that need a visit sooner based on what the imagery shows.

Harvest Compliance runs that comparison quarterly, checking actual cut boundaries and riparian buffers against the permitted plan and handing back a reviewable list of overcut area and buffer incursions. It doesn't replace the field visit. It narrows down which files earn one before the next scheduled round comes around.

The short version

Set a base cycle the program can actually staff. Shorten it for terrain, operator history, and amendment activity. And don't let the gap between scheduled visits be the only window in which an overcut goes unnoticed.
