Natural regeneration

Count seedlings and saplings by species and height on small plots, and see stocking, the share of plots adequately stocked, what is getting away above browse height and — where recorded — natural versus planted stems.

MethodWhereWhat it says
Species × height class provisionalThe default (recommended everywhere but England, Scotland & Wales and France, Belgium & Luxembourg)Stocking, % of plots adequately stocked (default threshold 2,500 stems/ha from 20 cm), share above browse height, natural vs planted
Saplings — FC Information Note 45England, Scotland & Wales (transformation to CCF)Saplings (≥ 130 cm tall, < 7 cm DBH) per ha against 2,000/ha; the simple and complex structure rules
AFI sub-plotsFrance, Belgium & Luxembourg, with the AFI stand methodThree 1.5 m sub-plots per AFI plot, four height / diameter classes; no adequacy threshold — follow the trend

Record in the field

Field app (Android)Regeneration plot visit.
Field app (Android)Seedling / sapling tally.
  1. On each regeneration plot (2 m radius by default, nested in the stand plot) record competing vegetation and a photo. Record empty plots — they count.
  2. Tally by species and height class, with how many have the leader browsed, and the origin — natural, planted or unknown. Birch and willow often seed in at planting: mark unknown rather than guess.

Web appStocking, species, origin, and stems by species × height class.
  • Plots adequately stocked is judged against your target % (default 70 %).
  • Getting away — the share above browse height (≥ 130 cm): the stems that have escaped browsing.
  • Origin — natural, planted and unknown stems, and the number of naturally colonising species.
  • FC IN 45: simple structure — ≥ 2,000 saplings/ha overall, ≤ 10 % of plots empty and ≥ 1,000/ha in the rest, 10–15 years after the seeding felling; complex — 10 % of plots at 2,000/ha early, rising to 50 %. The large-sapling share should rise.
Provisional defaults

Irish guidance sets no natural-regeneration stocking standard; 2,500 stems/ha mirrors the planting rate in the DAFM Forestry Standards Manual. Set your own threshold and height classes in the objective.

What it doesn’t do (yet)
  • No seedling identification help beyond the species list; record what you can name.
