How to… Identify Hedgerow Plants

Whizzing past our car windows, naturally bordering our fields and gardens, or providing a home for wildlife. Often going unseen and unnoticed, hedgerows are a widespread and overlooked habitat right on our doorsteps. Bountiful and bursting with life, each hedge is unique from the next, with a story to be told and a world to be explored.

Blackthorn 5

From butterflies and birds to hedgehogs and dormice, an incredible number of species rely on the plants in our hedges for their survival, such as food, shelter, and corridors along which to travel. They do not just play a role for wildlife though, holding value in the wider landscape, providing us with services such as stopping soil erosion and buffering pollution. In this way, hedgerows have been important for humans and wildlife alike for hundreds of years!

The first hedgerows can be dated back to the Bronze Age, when farmers cleared woodland to grow crops, leaving carefully maintained strips to act as boundaries. Some of these strips of ancient woodland can still be found today! Since then hedges have grown in popularity, but following the Second World War, many were ripped up to provide more space to grow food and for development. Despite approximately half of all hedges in Britain being lost during this time, thankfully the remaining were given protected status in 1997.

The hedgerows rolling across our countryside today are a piece of history, full of life and colour and provide us with a whole host of resources. So, why not try and see this for yourself, and take a moment to see what you can find in a hedgerow local to you? To help, here’s my simple guide to identifying some of our iconic hedgerow species.

How spring happened 2017-2019

Over the last few years, I have taken part in recording how spring has unfurled at my home in Dorset, for a citizen science scheme. As at the end of each spring I upload my results to an online site, in 2017 I decided that I should be writing my observations down for myself in my wildlife journal, making it easy to look back on them in the future.

Now I have recorded dates for many different wildlife spring events, from trees coming into leaf to the return of migrants, for 2017, 2018, and 2019. So here, I want to take a moment to look back at these and reflect on what they may show about spring and its current emergence, and if there is anything interesting we can take from this.

Trees

In my local area, you can find a large variety of native and non-native tree species. Over the last 3 years, I have consistently made observations for 5 tree species: ash, sycamore, horse chestnut, pedunculate oak and silver birch.

25_05_19_Outside

For the 5 tree species, some similar patterns can be observed from my recorded spring dates for the last 3 years. In 2018, a colder winter was experienced, with heavy snowfalls taking place in January, February and March. Evidently this had an effect on the timing of budburst, first leaf and first flowering for tree species, in comparison to the year before.

Budburst was 36 days later for ash trees (27/04/18), 10 days later for sycamore trees (08/04/18), 19 days later for horse chestnut trees (20/03/18), 21 days later for oak trees (18/04/18), and 26 days later for silver birch trees (12/04/18). The same amount of lateness was also seen with the first leaf and first flowering for these tree species in 2018.

19_04_19_Farm_Oak_Tree_2

Due to the weather of spring 2018, this meant that when looking at how this year’s spring unfurled (2019) in comparison to last year, predictably budburst, first leaf and first flowering took place 4-53 days earlier than 2018. When comparing 2019 with 2017 though, I am able to get an idea of the average trend for the three years. For example, ash and silver birch events are getting later, as are horse chestnut flowering and sycamore first leaf. Sycamore, horse chestnut and oak generally show a trend though of spring events getting earlier, from a couple of days to a month.

Shrubs

For shrubs, the selection I have been observing during spring each year are: blackthorn, dog rose, elder, hawthorn and lilac. From 2017-2019, a similar trend was predominantly observed in these species as with tree species.

In comparison to 2017, blackthorn first flowering was 14 days later in 2018 (30/03/18), elder budburst was 9 days later (13/03/18), elder first leaf was 23 days later (30/03/18) , hawthorn budburst was 33 days later (02/04/18), hawthorn first leaf was 6 days later (08/04/18), and lilac first flowering was 27 days later (07/05/18).

Then when looking at 2019, spring dates were earlier in comparison to 2018, with blackthorn budburst, first leaf and first flowering being 20, 9 and 29 days earlier, dog rose budburst, first leaf and first flowering being 22 and 29 days earlier, elder budburst, first leaf and first flowering being 9, 24 and 8 days earlier, hawthorn budburst and first flowering being 36 and 13 days earlier, and lilac first flowering being 14 days earlier.

Also, similarly to tree species, blackthorn and elder both showed that from 2017 to 2019 spring events have become earlier on average. Hawthorn and lilac showed the opposite trend though, with hawthorn first leaf and first flowering becoming later over the 3 years on average, if only by 7-13 days.

Flowers 

In comparing spring between 2017, 2018 and 2019, it is evident that for many plant species the same trends have been shown from year to year. This is not true for all though, as between bluebells, cuckooflowers, lesser celandines, oxeye daisies, snowdrops and wood anemones, flowering times varied from being later in 2018 and earlier in 2019, to being earlier overall, or being similar overall.

22_06_19_Farm_Chalk_Mound_Oxeye_Daisies_10

  • Bluebells flowered 17 days later in 2018 (13/04/18) than 2017, and then 10 days earlier in 2019 compared to 2018. From 2017 to 2019, this was 7 days later overall.
  • Cuckooflowers flowered 16 days later in 2018 (20/04/18) than 2017, and then 12 days earlier in 2019 compared to 2018. From 2017 to 2019, this was 4 days later overall.
  • Lesser celandines flowered 5 days earlier from 2017 to 2018 (24/02/18), followed by another 13 days earlier in 2019.
  • Snowdrops flowered 10 days earlier from 2017 to 2018 (10/01/18), followed by another 7 days earlier in 2019.
  • Wood anemones flowered around a similar date at the beginning of March each year.

12_04_19_Horseshoe_Wood_Anemone_7

  • Oxeye daisies flowered around a similar date at the end of May each year.

Grasses

Grass species also showed a differing trend to tree and shrub species for 2017-2019, with a united pattern of flowering later each year. When observing spring events with grasses, I observe from year to year 4 species: cocksfoot, meadow foxtail, timothy, and yorkshire fog.

22_06_19_Farm_Chalk_Mound_Yorkshire_Fog_Grass_2

Only timothy had observations made for 2017, and so in comparing with 2018, it was found to have flowered 18 days later (18/05/18). This is in line with comparisons between 2018 and 2019, where it was found that cocksfoot flowered 4 days later (30/05/19), meadow foxtail flowered 14 days later (15/05/19), timothy flowered 23 days later (10/06/19), and yorkshire fog flowered 14 days later (12/06/19).

Birds

Though I have started increasing my recordings of different bird species during spring, I only have records for 2+ years for rooks, blackcaps, chiffchaffs, house martins, song thrushes, cuckoos, and swallows.

  • Following the first snowfall of the year, rooks were first seen to be nest building 16 days earlier in 2018 (04/02/18) than 2017, but with no snow, this was 11 days later in 2019.
  • Blackcaps returned to my local area 12 days later in 2018 (11/04/18) than 2017.
  • Chiffchaffs returned 13 days later in 2018 (26/03/18) than 2017, following the last of the snow and cold weather. Consequently, in 2019 they returned 8 days earlier than 2019 (15/02/19), closer to the 2017 date.
  • House martins returned 12 days later in 2018 (25/05/18) than 2017, whilst being 31 days earlier in 2019 than 2018.
  • Male song thrushes were first heard singing in 2018 on 28/01/18, 8 days earlier than 2017. In 2019, this occurred a lot earlier though, 30 days earlier, falling on 29/12/18.
  • Male cuckoo heard calling at a similar time at the end of May in 2018 and 2019.
  • Swallows returned to my local area at a similar time at the end of March/beginning of April in 2017, 2018 and 2019.

Insects

22_06_19_Garden_Yellow_Flower_Bee

In line with tree and shrub species, the first sightings recorded each spring of insects followed a general pattern of emerging later in 2018 than 2017, and earlier in 2019 than 2018. This was true for:

  • Brimstone butterflies – 13 days later on 14th April 2018 and 47 days earlier on 26th February 2019
  • Peacock butterflies – 14 days later on 20th April 2018 and 26 days earlier on 25th March 2019
  • Small tortoiseshell butterflies – 31 days later on 26th April 2018 and 25 days earlier on 1st April 2019
  • Speckled wood butterflies – 20 days later on 26th April 2018 and 4 days earlier on 22nd April 2019
  • Orange tip butterflies – 28 days later on 4th May 2018 and 33 days earlier on 1st April 2019
  • Red admiral butterflies – 27 days earlier on 22nd April 2019 
  • 7-spot ladybirds – 19 days later on 25th April 2018
  • Queen wasps – 47 days earlier on 31st March 2019
  • Red-tailed bumblebees – 13 days earlier on 21st April 2019

Summary

With my love of spring, each year I have enjoyed recording the dates of when things happen during spring, such as the first swallow, first leaf or first elder flower. It has been satisfying now to be able to take a moment to put a few of my records together and take a look at how spring has unfurled over the last few years and what this could mean.

For some species, events are getting earlier, probably due to warmer temperatures earlier on in the year and during the winter before. For others, they are in fact getting later, which will be related to other weather and environmental factors here and further afield. Either way, the ‘norm’ is changing and it will be interesting to see how this could progress over the next few years to come.
