A couple of weeks ago I came across
a Forum called `Our Nottinghamshire`(1) which has an article in it titled `The
strange case of the Midwife Toad .An invader from Yorkshire via the Continent`. Dated March 21st
2013. I am including here the most salient points in the article,including a
link to a photo (2) of the pond from whence the toads
emerged.
“Several accounts in the early 2000s
record the finding of an unusual toad, smaller than our usual toad as well as
reports of a strange bell-like sound, a sound unfamiliar in our Isles, suggested
something unusual was living in an obscure part of the county. In particular,
the sightings and sounds have been recorded around Worksop such as along
Owdy Road , Carlton in Lindrick, where squashed toads on
the road were finally identified as the species.
The origin of these aliens can be
traced to either 1878 or 1898, when a nursery firm Horton and Smart accidentally
introduced the species to their Bedford site as
eggs on aquatic plants from France . They would have remained
there and subsequently died out in 1922 when the pool they had colonised was
filled in by Bedfordshire county Council, if it were not for a W S Brocklehurst
(3) collecting a dozen for his private pond. From this colony,his son Robert
Brocklehurst brought 5 toads and 12 tadpoles from his father`s garden to his
house at Woodsetts near Worksop...In the Spring of 1947 Mr Brocklehurst brought
plants from his father`s pond at Bedford, and then in August he introduced the
toads. He states that:
“ Nothing more was heard or seen of
them that year.In the Spring of 1948 the toads were heard croaking and they
continued to call all through the summer. In August about twenty tadpoles from
Bedford were
introduced. Most of them were well-advanced in growth and it is believed that
they underwent metamorphosis that year. On april 15,1949, a toad was heard
croaking,not at the pond site but from a large rockery built by a former owner
of the house and standing in another part of the garden some 95 yards away from
the pond.Croaking continued throughout the summer, both from the pond site and
from the other rockery.”
A mild February in 1950
meant that two toads were heard calling although he noted they were not usually
active until late April and May. What is well known to naturalists is the toad’s
unusual breeding where after normal copulation the male takes the string of eggs
around his legs and carries them with him until they hatch, although strangely
they do not always live near water and can be found anything up to 25 yards from
any water.
A Paul Batty on a herpetological website notes that no one knows how many colonies there are, but is clear they are spreading and establishing more in both Woodsetts and into Nottinghamshire. As an introduced species of course they receive no protection and understandably some people may be reluctant to reveal the survival of the species. However, soon the bell like sound of this rather amiable alien may be more familiar in the county.

same Brocklehurst who introduced wallabies into the Peak District via a private
zoo.
