Prestwood Nature Activities in 2023

What people say about us

Here is some of the feedback we have had from our members

"Karen’s seasonal hedgerow walks are wonderful! My husband and I have participated in several and really look forward to attending more.
Karen is incredibly knowledgeable and has a wonderful manner. She engages people of all ages - for the oldest to the youngest - and we all have fun, as well as learning a lot "

Hedgerow Walk 2nd April:

"We’ve thoroughly enjoyed all the seasonal hedgerow walks we’ve done with Karen.
Karen is amazingly knowledgeable about all things botanical and patiently answered all my kids’ questions without dumbing down the science while also keeping the adults"

Wildflowers of Frogmore Meadows - Thursday June 8th

Led by Tony Marshall and Karen van Oostrum.


Come and see a wealth of wildflowers and pollinators in this lovely nature reserve

The Central Chilterns Botany Group visits local sites to record native wild plants.


On 8 June, the group, led by Tony Marshall, Karen van Oostrum and the reserve warden will visit Frogmore Meadows in Chenies.


Frogmore is a nature reserve of the Herts and Middlesex Wildlife Trust reserve. It consists of three ancient meadows (chalk, neutral and acid) which have never been ploughed, fertilised or sown, resulting in a wide array of beautiful wildflowers visited by many different pollinators.


Members of Prestwood Nature can join this visit. If you are interested, please register through Eventbrite using this link.


If you sign up you will be sent more information closer to date on where to meet – we will try to travel using as few cars as possible to limit our impact and ensure we can park at Frogmore.

The Lure and Lore of Wildflowers - Sunday August 13th

Led by Roy Vickery


11:30 am – 1:30 pm    and    2:30 pm – 4:00 pm


Learn about the amazing myth and magic associated with some of our wild plants.


Roy Vickery is an experienced botanist who worked at the Natural History Museum for 42 years. He has collected and written extensively about the use and folklore of native plants. He’s an experienced lecturer and walk leader on plantlore.


Roy is coming to Prestwood to take us on a gentle stroll around Prestwood Local Nature Reserve (aka the Picnic Site) telling us about the fascinating folklore of some of our best loved wildflowers. Prestwood Nature Reserve consists of a combination of chalk grassland and scrub areas that make it abundant in wildlife with an incredible diversity of wildflowers.


If you are interested please register through Eventbrite using these links:

Morning walk (11.30 a.m. start)

Afternoon walk (2.30 p.m. start)  [sold out]


The what3words location for the Picnic Site is ///linguists.inhaled.fallen. There’s parking at the entrance.

Fungi Foray - Saturday 7th October

We hope to hold a Prestwood Nature Fungi Foray on Saturday 7 October from 10am to 12am, led by Tony Marshall. The walk is open to members and their friends or family.  


As we will not know whether there will be sufficient fungi to warrant a foray, we will have to confirm details the week before. The foray will in all likelihood be held at Monkton Wood between Great Hampden and Speen, but as parking is limited, we would have to ask people to share no more than six cars. 


If you would like to come, please register your interest here.


We will then be back in touch by email in the week before the Foray to confirm whether the walk will go ahead and where to meet.
