In the field
Access, identification and rules in the field
Our flight, field and detection dog teams work in forests and on farmland throughout Germany every week. This page explains the legal basis on which we use forest roads, how our teams are identified and which rules apply during deployments.

You met us on your land?
Our teams work in forests, meadows and along field margins every day. This is a normal part of our assignments. Feel free to talk to us: everyone in the field can tell you straight away what they are doing, for whom and on what legal basis.

The legal basis for our presence on your land
| Entering forests on foot | § 14 Federal Forest Act and the respective state forest law; in the Rhön tri-state area: Hessian, Bavarian (Art. 13) and Thuringian forest acts | Coordination with owner or district forester |
|---|---|---|
| Meadows and open countryside | § 59 Federal Nature Conservation Act: paths and unused land | Farmed meadows and fields only with the farmer’s consent |

Assignments elsewhere in Europe: rights of access
Access to forest and countryside is regulated separately in each country. For surveys we additionally obtain the owner’s consent; drone flights are governed EU-wide by Regulation 2019/947.

Access permit
Legal basis for using forest roads
Driving on forest roads is generally restricted by the state forest laws and only permitted with authorisation. We therefore work exclusively on behalf of or with the consent of those entitled on site: forest owners, hunting district holders, hunting tenants and farmers.
Assignment and consent
Every assignment is based on a commission or the consent of the forest owner or farmer. Permission from the owner is obtained for driving on forest roads; official surveys are carried out only on behalf of public authorities.
Network of hunters and farmers
We work closely with a large network of hunting tenants, hunters and farmers in the region, so access routes, quiet zones and hunting dates are known and agreed before every assignment.
Notification of the district forester
Every assignment is reported to the responsible district forester and, where applicable, the holders of hunting rights at least 48 hours in advance. During calamities, the notice period is reduced to 24 hours.
Europe
Assignments elsewhere in Europe on request
EU drone regulation 2019/947 applies in all member states. Our operational authorisation in the specific category is recognised in the destination country after notification of its aviation authority. Vehicles, trailers and dog boxes travel with the team, and the sample chain remains complete all the way to the accredited partner laboratory.

Detection dogs
Deployment of the detection dog unit
Detection dogs check on the ground what the aerial analysis has delineated as suspect. They find fresh boring dust, carcasses or scat even where cameras have no view: beneath the canopy, in thickets and at the stem base. Every search follows a defined procedure.
- 1Assignment order and coordination with the district forester and holders of hunting rights
- 2Coarse search of the suspect area from the aerial analysis
- 3Fine search and passive indication at the find location
- 4Location fix, photographic documentation and sampling where required
- 5Handover of find record, GPS track and samples to the client and laboratory

Deployment rules
- Search phases of 30 to 45 minutes per dog, followed by a break of at least 15 minutes; no more than four hours of search work per day.
- Above 25 °C air temperature, searches take place only in the early morning and evening. Deployments are suspended in storms, heavy rain or at fire danger levels 4 and 5.
- The search direction is set according to wind and terrain, working into the wind wherever possible.
- During the breeding and rearing season, dogs search only after coordination with the district forester and only on a long line.
- Every search is recorded as a GPS track with duration, temperature and wind direction and handed over to the client.
- An indication only counts as a finding once it has been confirmed by visual inspection (boring dust, entry holes) or laboratory analysis.
