CHILTERN HIGHLIFE by Colin Williams, Reserves Ecology Officer

Chiltern gentians in good numbers; BBOWT’s last annual census
revealed more than 5,000 flowering plants. As a successful
coloniser of bare and disturbed ground it has a fondness for
growing alongside the network of well-worn paths around the
open chalk grassland areas of the nature reserve. Conveniently,
this makes them easy to spot as you stroll through.

    Be warned, however, as their identification is not straight
forward! Chiltern gentians often grow in the same locations
as the almost identical autumn gentian. To complicate matters
further, they can breed with each other to produce hybrids
between the two.

    So how do you know if you are looking at a true Chiltern
gentian? The answer is to get up close to the flowers once you
have taken in the impressive vista. Chiltern gentians are usually

Dragonfly or damselfly?                                                                           Wells Farm supports numerous farmland bird species.

Dragonflies and damselflies are insects of the order Odonata,
meaning ‘toothed’ and referring to their strong mouthparts.
At first glance it’s hard to tell them apart. But look closer and
the differences between these two sub-orders becomes clear.
