Wenthillside is a privately owned and managed eleven acre conservation site in West Yorkshire. Butterfly Conservation members can visit the land most times by prior arrangement (as it is fenced and has locked gates). It is located about 2 miles South of the M62/A1 crossroads and half a mile NW of Wentbridge on Moor lane grid ref. SE4718. Sat nav. postcode for Moor lane Wentbridge WF8 3JN Off road parking on grass is available and there are several log seats around the site for either picnicking or just observing.
The majority bought in 2013 and the lower field in 2017, mostly down to rough un-farmed grass with several small areas of trees and scrub, the lower 3.3 acre field bare agricultural destined to be a wildflower meadow. A SW facing magnesium limestone hillside with a large and varied wildlife content. To date 23 different species of butterfly, 19 regularly, including a large colony of Marbled White and several Purple Hairstreak. 53 species of moth, 166 species of plants and flowers, 44 species of fungi and 34 species of grasses/sedges long with 22 species of trees and bushes with much more to be discovered and documented.
All the boundaries are being gradually hedged with a variety of trees and bushes to further encourage biodiversity and to give some protection from our Westerly winds. Several access paths have been made but many areas are steep and uneven with occasional rabbit holes and areas of nettle/thistle and blackberry.
From the hilltop there are long distant views both West to the Pennines and East to the many wind turbines in the Humber area.
WenthillsideUpdate May 2020
Butterflies seen so far this year, maximum at any time.
Peacocks 20+ my best spring, commas slightly down at 6, small tortoiseshell down at only 2 (but lots everywhere else I’ve been). Only 1 speckled wood, orange tip 20+ males and more GV, small and large whites than last spring. Brimstone often float through but only seen 2 at once.
Moth total now at 136 having seen a blood-vein 2nd May.
All grass areas that were cut are showing good numbers of target wildflowers especially the violets.
Wild primroses are flowering well and there are some spreading.
Trefoils are coming into flower in several areas, a bit early to assess success.
A total of 604 hedging/tree plants have been planted this winter, mostly hawthorn, blackthorn, hazel and small numbers of 7 other species including small leaved elm.
Some of the older hawthorns have been cut and laid, with most being successful, an ongoing project.
Grasses are steadily covering the bottom field but still a long way to go.
Another 120+ cowslips given by a local grower planted.
A brushwood pile next to the car park has a dunnock and robin nesting in it.
Work on fencing, rustic style, around the car park is just about complete.
The V63 botanical recorder sent me a link to “Geology of UK” and actually the slope of hill is sandstone of the latter end of the coal measures with a cap of Permian limestone at the ridge. As there is a lot of limestone spill over and water run down the slope the topsoil is in the lime range and not acidic. This means that there could be many different soil Ph levels all over the site.
Early summer 2013, with little or no Westerly winds, saw a Ringlet population in the thousands on one day but the winds since have limited numbers to the low hundreds in any one day. Scrub removal at the lower part of the hill has seen skipper and Meadow Brown numbers increase with definite Essex Skipper on site. Spring sees large areas of Bluebells which bring in Brimstones and recent plantings of buckthorn will hopefully encourage a permanent population. Spring also sees large numbers of Orange-tip on the plentiful hedge mustard and all three whites are common a little later in the year.
