2 years into the process would likely have been after they hired their experts and did the study, there would have been zero point doing the study before the route was finalised as they could have ended up doing hundreds of studies for areas they didn't end up going near.Nah this is misleading AF - you're not talking about something that was planned for and budgeted well in advance, you're just highlighting that the incident being referred to occurred 10 years ago - and in that case so what? This is a big project over many years, this being used as an example of initially unforeseen expenditure is still valid no?
HS2 was announced as going ahead 12 years ago, so this would be 2 years into that process and seems like it's still a legitimate example of something they'd not have initially estimated right? Or if not then provide an actual explanation of why as simply saying the event happened 10 years ago doesn't negate anything here.
At the very minimum with any ecological study you tend to need to do it over the space of a full year, or the time frame in which the animals you are checking on would be in the area, it's utterly pointless to see if something might affect the migration route of an animal that is there for 3 months in winter, if you do the study in the summer, and for animals that might be in the area year round you need to allow time to see how they behave in that area all year round as a lot tend to change habits with the seasons (they might travel much further in the winter to reach a different food source, or change where they spend the night so they're more protected from the elements).
