Defining NTFPs in the Polish Context
The FAO defines non-timber forest products as "goods of biological origin other than wood, derived from forests, other wooded land and trees outside forests." In Polish forestry practice, the term użytki uboczne lasu (secondary forest products) covers roughly the same ground, though the administrative categories differ slightly from FAO usage.
Polish State Forest statistics group secondary products into:
- Forest fruits and seeds (mushrooms, berries, nuts, cones)
- Medicinal and aromatic plants (bark strips used for tanning, herbs)
- Resin and sap (including birch sap and pine resin)
- Moss, lichen, and decorative plant material
- Wild game and fish are tracked separately
Published data from Lasy Państwowe annual reports shows that mushroom and berry collection accounts for the largest volume of documented secondary product activity in Polish State Forests, though official figures capture only permitted and commercially licensed collection. Personal use collection by members of the public is not systematically tracked.
Access Rights: What the Law Permits
Under Article 26 of the Polish Act on Forests (Ustawa o lasach z dnia 28 września 1991 r.), State Forests in Poland are generally accessible to the public for recreational use and for the collection of fruits, mushrooms, and plants for personal use, unless specific areas have been closed to public access for silvicultural, protection, or safety reasons.
Several important limits apply to this general permission:
- Collection is for personal use, not commercial sale or resale
- Activities that damage trees or soil — including bark stripping, root excavation, and drilling into living wood — are not covered by the general public access provision
- Closed areas include regeneration plots, seed orchards, experimental areas, and sections temporarily closed for logging operations
- Nature reserves within or adjacent to State Forests operate under separate strict protection rules
Practical note: The distinction between "collecting what the forest produces" (mushrooms, fallen cones, ground berries) and "intervening in a living tree" (tapping sap, stripping bark) is significant in Polish forest law. The latter always requires specific authorisation from the relevant Forest District.
Birch as an NTFP Species in Poland
Silver birch is one of the most widespread tree species in Polish forests, covering a substantial proportion of the total forested area particularly in the northeastern and central regions. As an NTFP source, birch contributes across several product categories simultaneously: sap in spring, bark throughout the growing season (with summer being optimal), leaves and catkins used in folk herbal traditions, and wood charcoal produced from thinning material.
The species' ecological role also extends to NTFP availability indirectly. Birch stands create specific light and soil conditions favoured by certain edible mushroom species, including chanterelles (Cantharellus cibarius) and various boletus species, making birch-dominated stands productive foraging areas beyond their direct products.
Ecological Principles for Sustainable Collection
Sustainable NTFP collection from birch forests rests on a few well-documented ecological principles:
Not exceeding regenerative capacity
Individual trees and forest stands can recover from moderate extraction, but this capacity has limits. For sap, research on wound compartmentalisation suggests that annual tapping of the same tree at the same location without rotation can lead to persistent internal defects over a decade or more. Distributing harvest across multiple trees and rotating tap locations helps maintain stand health.
Maintaining structural integrity of the forest
NTFP collection that damages understory vegetation, compacts soil through repeated heavy foot traffic, or opens bark wounds that allow fungal pathogens to enter can degrade habitat for other species. This is particularly relevant in older birch stands where dead wood and bark texture support specialised invertebrate and lichen communities.
Respecting phenological windows
Most NTFP collection is most sustainable when carried out during the species' natural production peak — when the resource is available in abundance and the plant is physiologically equipped to regenerate the harvested tissue. For birch sap, this means the pre-bud-burst window; for bark, the active growth season when the outer periderm separates cleanly.
Commercial NTFP Activity in Poland
Small-scale commercial birch sap collection under Forest District agreements exists in several parts of Poland, particularly in the Podlaskie and Warmia-Masuria regions where birch cover is high. Licensing terms vary by district and typically specify the number of trees, the collection period, wound treatment requirements, and reporting obligations.
The FAO's European Forestry Commission has noted in regional assessments that Poland has potential for expanded NTFP production given its forest cover and birch resource base, but that regulatory fragmentation and the absence of standardised national NTFP frameworks limit consistent development. Current activity is distributed among many small operators rather than concentrated in large commercial enterprises.
