Before you buy

Who this is for

Made for

  • People who keep a record and want the reference already on the page
  • Teachers and parents doing a year of nature with a child
  • Anyone who prefers paper to another app

Not for

  • Anyone wanting a dated planner — these pages are deliberately undated so you can print them again next year

Everything here describes typical timing across Oklahoma, drawn from long-run records — weather, elevation and how close you are to water all move the real dates around. So the Oklahoma pages say "usually early May" and never "May 4th", which is not hedging but the most the data can honestly carry.

Where it comes from

Compiled from

USGS Breeding Bird Survey · State fish & wildlife agencies · USA National Phenology Network · Lady Bird Johnson Wildflower Center · Cooperative Extension (land-grant directory) · International Meteor Organization. How each of these is used in the Oklahoma edition, and which figures are measured rather than modeled, is set out in the methodology.

Questions

Before you decide

Is this specific to Oklahoma, or a national guide with the name swapped in?

It is built from Oklahoma's own data. Each month's reference side is written from Oklahoma's data for that month, not a national average.

Oklahoma spans several hardiness zones — which one does this cover?

All of them. Oklahoma runs 6a–8b, and the guide carries each zone's timing rather than picking one and hoping it fits your garden.

How accurate is the timing for Oklahoma?

It describes typical timing across Oklahoma drawn from long-run records, and because weather, elevation and habitat move real Oklahoma dates around it says "usually early May" rather than "May 4th".

Is it worth paying when the Oklahoma pages here are free?

The free Oklahoma pages are the month you are in; this is the whole Oklahoma year, planned before it arrives and printable, so you are not holding a screen in the garden.

Will it work for my part of Oklahoma, or just the big cities?

It is written at state resolution — Oklahoma as a whole, with regional notes where Oklahoma genuinely differs end to end, and nothing behind it is recorded finely enough to honestly promise more than that.

What format is the Oklahoma edition, and can I print it?

A PDF laid out for both Letter and A4, one page per sheet — printing it is the point, since the Oklahoma pages are made to be carried outside.

What if the Oklahoma guide is not what I expected?

Email hello@birchcompass.com within 30 days for a full refund on the Oklahoma edition, and keep the files either way — asking for them back would be theatre.
