Givens Fire & Forestry
Free calculators and a plant identifier for height, volume, cords, wildfire risk, and species ID — built for Montana landowners.
Free Planning Tools
Size up a tree, identify plants, estimate firewood yield, or screen wildfire risk at your address. Each tool stands alone — and your results are a useful starting point for removal quotes, defensible-space consulting, and mitigation work.
Height
Estimate tree height without climbing. Choose from five methods — angle, shadow, line-of-sight, clinometer, or triangulation — with metric and imperial units.
Volume
Got a felled tree and want to know how much firewood you’ve got? Enter bottom diameter, top diameter, and height to get volume and cord estimates in real time.
Wildfire risk
Enter a property address for fuel, slope, weather, and a surface fire risk score — a practical first look before defensible-space consulting or fuel mitigation on your land.
Species ID
Snap or upload a photo to identify plants and trees — then see Montana-specific fire-risk notes for species near your home or in your defensible space zones.
Take it offline
All four field tools in one app — tree height, cords, wildfire risk, and plant ID.

Built for the field
Free calculators for timber, firewood, and wildfire screening — useful on their own, and a solid head start before removal, defensible-space consulting, or fuel mitigation work.
Turn felled timber into cord counts before you stack, split, or quote a delivery — no guesswork on volume.
Screen wildfire risk at your address, then bring the results to a defensible-space consult — we’ll walk the property and build a real mitigation plan.
Measure height for removal tiers, run quick volume checks in the field, and walk into a quote with numbers — not ballpark guesses.
Need more than a calculator?
Tree removal, defensible-space consulting, fuel mitigation, and cleanup across Southwest Montana. Bring your calculator results — we’ll take it from there.
