Guide: Conservation Sites · approx. 5 min read
Ask any reserve manager what keeps them up at night and vehicles will be near the top of the list. Off-road bikes cutting ruts through meadow. 4x4s on wet grassland. Hare coursers using a field entrance at 2am. A van-load of rubble tipped in a gateway on a quiet lane. Each one costs money to put right, and some of the damage to habitat can't be put right at all.
This guide covers what actually works at the entrance, and where money gets wasted.
Start with how they're getting in
Before specifying anything, walk the boundary and work out where vehicles are really entering. On most reserves it's a short list:
- The main car park, used out of hours once staff have left.
- Service and management tracks with a padlocked field gate that's either left open or has had its lock cut.
- Field entrances off lanes, often just a gap, a broken gate or a gate tied shut with baler twine.
- Weak points in the boundary where a hedge or ditch can be driven around a gate.
There's no point fitting a strong gate if a vehicle can drive round it. Posts, bunds, boulders or a short length of fencing either side often matter as much as the gate itself.
Why padlocked field gates fail
The classic answer is a steel field gate and a padlock. It fails for predictable reasons: the lock gets cut, the combination gets shared around, or a volunteer or contractor leaves it open because they're coming back later. And once there are dozens of keys in circulation, you've no idea who has one.
An automated gate that closes itself behind every vehicle removes the "left open" problem entirely, and access control removes the key problem.
What works
Automated gates that close behind every vehicle
An automated gate is only open for as long as it takes to drive through. For reserves we usually recommend our EstateGuard five-bar style gates. They look at home on a rural track, but they're galvanised steel with an underground crossbar on hinging models to resist ground movement and tampering.
Access control instead of keys
With GSM access control, authorised users open the gate by phone. Lose a volunteer, delete their number. No locks to cut, no codes to leak, and a log of who came through.
Timed car park closing
Set the visitor car park gate to close at dusk and open in the morning. Staff can still override it by phone for events or emergency access. It stops the car park becoming a night-time venue without anyone needing to drive out and lock up.
Solar power where there's no mains
The entrances that need securing are usually the remote ones. Off-grid solar runs the gate and access control with no cable trench, which on protected ground is often the difference between a project that goes ahead and one that stalls in consents.
Where money gets wasted
- Height barriers alone: they stop vans and caravans, not cars, bikes or 4x4s.
- Gates without the boundary either side: if you can drive round it, it isn't a gate.
- CCTV at remote entrances on solar: continuous recording draws more power than a panel can reliably supply in winter. It can be done, but it needs its own power planning. Don't assume the gate's solar kit will run it.
- Industrial gates in the wrong setting: palisade and heavy commercial gates can draw objections on designated sites and from visitors. A gate that suits the landscape gets approved faster.
Don't block the public
If the track is also a public footpath or bridleway, walkers, riders and cyclists still need to get through. A pedestrian or bridle gate alongside the vehicle gate keeps the right of way open, and any new gate across a right of way may need authorisation from the highway authority. We cover this in more detail in our protected sites checklist.
