In terms of visitor numbers, the zoo had an excellent start to 2018. In just the first two months of the year they welcomed 78% more visitors compared to the same period in 2017. In 2018, they also had the highest visitor numbers in Feb half-term week on record (which has since been surpassed again in 2019) and the May Day bank holiday weekend attracted the highest visitor numbers for more than 20 years. Things were looking promising and the zoo had even budgeted to achieve 315,000 visitors by the end of the year.
However, as you can see, despite a brilliant start, they did not manage to achieve this. This was predictable after the zoo announced to the public, on 30th November, that one of their snow leopards had escaped through keeper error and sadly the zoo was forced to euthanise it - possibly the worst PR any zoo could ask for.
Unfortunately, even if people were upset at the zoo or not, the public tend to stay away from turbulence and visitor numbers in December must have been minimal. It could be viewed that the fact the zoo's normally extremely popular Santa's Grotto achieved approximately £10,000 less income in 2018 is some evidence for this.
On the plus side, the zoo did achieve a higher overall total income in 2018 than in 2017, despite visitor numbers not being as high.
Going back to the snow leopard incident, the zoo had a full zoo inspection carried out by the zoo's licencing authority, Dudley Metropolitan Borough Council, in February 2019.
The inspectors noted:
'Concerning the escape of the snow leopard into the zoo on 23/10/2018 the inspectors were shown a detailed report of the incident, made a thorough examination of the house, enclosure and the improvements to the security arrangements were demonstrated. The inspectors agree with the management that the escape protocols in place at the time worked efficiently and that a detailed report of the incident occurred. Whilst the risk of human error can never be totally eliminated, the new electronic warning system should further reduce these risks. As there is no "off the shelf" system available, management and staff are to be congratulated for developing this in house system, which after fine tuning, is planned to be installed in other houses of Category 1 animals. Its uptake may well be considered in other zoological collections.'
