Follow-up control of seedlings need only occur every second year.

If follow-up controls are not implemented, the problem can be exacerbated.

Follow-up control including spraying of regrowth will be necessary.

Marking each control site is, therefore, important to allow follow-up control measures and rechecking.

Hot fires, however, present dangers to other park values whereas mild fires require more follow-up control.

It was seen as the first of many coordinated, periodic, population knockdowns that would serve as follow-up control in strategic areas.

If appropriate, burning may be used to promote mass regeneration of seedlings to reduce seedbanks but follow-up control must take place.

Five of five animals re-tested in a follow-up control test (i.e. without treatment) had VF.

Surveillance results subject to further compliance action (violative results) must be verified by prescribed confirmatory techniques before any follow-up control action is taken.

This system of follow-up controls is seen as a very important instrument to harmonise the marketing conditions in the Member States and is therefore also endorsed in the internal market.

It must apply more boldly than before for interim injunctions by the European Court of Justice, and essentially, follow-up controls must become the rule when deficiencies are identified, and the costs must be charged to the defaulting Member States.

Furthermore, a defect was discovered in the Nose Wheel Steering (NWS) follow-up control valve that caused vibration of the NWS and damaged the dowel pins in the steering gearbox leading to erratic changes in the NWS datum making the aircraft difficult to steer.
